motang writes: Canonical, the sponsor of widely popular Ubuntu Linux, plans on shipping the next LTS in two versions. In addition to the traditional version, there will be one immutable desktop OS flavor. From Canonical blog: The technology behind snaps extends beyond the distribution of desktop applications however. With Ubuntu Core this philosophy of security and stability applies equally to the components that make up the entire Ubuntu operating system. Rather than treating the OS as a single immutable 'blob,' Ubuntu Core breaks it up into discrete components. The base of Ubuntu Core, for example, is built on four primary snaps:

Gadget: Defines the system's bootloader, partition layout and default configurations for snaps.
Kernel: Containing the Linux kernel and hardware drivers.
Base: A minimal Ubuntu OS image containing only the necessary services and utilities to support the applications running on top.
Snapd: Manages the lifecycle of all snaps in an Ubuntu Core system.
Additional OS snaps can then be layered onto this image to enable other elements of the operating system such as a desktop environment.

prisoninmate shares a report from 9to5Linux: The Ubuntu Cinnamon Remix distribution has become an official Ubuntu flavor and will join the rest of the flavors starting with the upcoming Ubuntu 23.04 (Lunar Lobster) release. Created and maintained by members of the Linux community, Ubuntu Cinnamon Remix is an Ubuntu derivative that features the modern Cinnamon desktop environment developed by the Linux Mint team. Cinnamon Remix aims to offer a traditional approach to the modern Linux desktop.

Until now, the maintainers of Ubuntu Cinnamon Remix did a very good job keeping up with all upstream Ubuntu releases, even offering a custom version of the official wallpaper of each new Ubuntu release to match the Cinnamon desktop environment's style. Ubuntu Cinnamon will not be the only new official Ubuntu flavor this Spring when Ubuntu 23.04 will be released as the maintainers of Ubuntu Unity have also managed to obtain official Ubuntu flavor status last year in September. As with Ubuntu Unity, the next step now for the Ubuntu Cinnamon maintainers is to bake daily ISO images in preparation for the upcoming Lunar Lobster release and maybe even take part in the Ubuntu 23.04 beta release later this week on March 30th. The latest Ubuntu Cinnamon Remix release and can be downloaded here.

"With an 8-core Rockchip RK3588S SoC, the Orange Pi 5 is leaps and bounds faster than the aging Raspberry Pi 4," writes Phoronix: With up to 32GB of RAM, the Orange Pi 5 is also capable of serving for a more diverse user-base and even has enough potential for assembling a budget Arm Linux developer desktop. I've been testing out the Orange Pi 5 the past few weeks and it's quite fast and nice for its low price point.

The Orange Pi 5 single board computer was announced last year and went up for pre-ordering at the end of 2022.... When it comes to the software support, among the officially available options for the Orange Pi 5 are Orange Pi OS, Ubuntu, Debian, Android, and Armbian. Other ARM Linux distributions will surely see varying levels of support while even the readily available ISO selection offered by Orange Pi is off to a great start....

Granted, the Orange Pi developer community isn't as large as that of the Raspberry Pi community or the current range of accessories and documentation, but for those more concerned about features and performance, the Orange Pi 5 is extremely interesting.
The article includes Orange Pi 5 specs:

• A 26-pin header
• HDMI 2.1, Gigabit LAN, M.2 PCIe 2.0, and USB3 connectivity
• A Mali G510 MP4 graphics processor, "which has open-source driver hope via the Panfrost driver stack."
• Four different versions with 4GB, 8GB, 16GB, or 32GB of RAM using LPDDR4 or LPDDR4X. "The Orange Pi 4GB retails for ~$88, the Orange Pi 5 8GB version retails for $108, and the Orange Pi 5 16GB version retails for $138, while as of writing the 32GB version wasn't in stock."

In 169 performance benchmarks (compared to Raspberry Pi 4 boards), "this single board computer came out to delivering 2.85x the performance of the Raspberry Pi 400 overall." And through all this the average SoC temperature was 71 degrees with a peak of 85 degrees — without any extra heatsink or cooling.

Liliputing.com has an update about the System76 Meerkat, which they describe as "a compact desktop computer with support for up to 64GB of RAM, up to two storage devices (for as much as 16TB of total storage), and up to an Intel Core i7 mobile processor. It's basically a rebranded Intel NUC." (Escept that System76 offers a choice of Pop!_OS or Ubuntu Linux pre-installed.)

"Previously available with a choice of 10th or 11th-gen Intel Core processor options, the Meerkat now also supports 12th-gen Intel chips." That means there are a total of 9 different processor options available. Prices start at $499 for an entry-level model with a Core i3-10110U processor, 8GB of RAM and a 128GB SSD. The prices rises by $50 if you want to go with a Core i3-1135G4 model, while prices start at $599 for a Meerkat mini PC with a 12th-gen Intel Core processor....

But the biggest difference is that Intel's 12th-gen processors introduce a hybrid architecture that pairs Performance and Efficiency cores, leading to much higher core counts for better multi-core performance.

An anonymous reader shares this report from 9to5Linux: After Canonical's announcement that future Ubuntu releases won't include Flatpak support by default, someone already made an unofficial Ubuntu flavor that ships with support for Flatpak apps preinstalled and working out of the box, called Ubuntu Flatpak Remix.

Meet Ubuntu Flatpak Remix, an unofficial Ubuntu derivative that doesn't feature support for Snap apps and comes with support for Flatpak apps working out of the box. Several key apps are preinstalled in the Flatpak format rather than as a Snap app, including the Mozilla Firefox web browser, Mozilla Thunderbird email client, and LibreOffice office suite.... Support for the Flathub portal is installed as well, so you'll be able to install more apps with just a few clicks.

Last week ZDNet reported Linux had added upstream support for the Apple M1 Pro, M1 Max, and M1 Ultra chips and then concluded that "newer Mac owners can look forward to running Linux on their M1-powered machines."

Saturday Asahi Linux called ZDNet's story "misleading and borderline false," posting on Twitter that "You will not be able to run Ubuntu nor any other standard distro with 6.2 on any M1 Mac. Please don't get your hopes up." We are continuously upstreaming kernel features, and 6.2 notably adds device trees and basic boot support for M1 Pro/Max/Ultra machines. However, there is still a long road before upstream kernels are usable on laptops. There is no trackpad/keyboard support upstream yet.

While you can boot an upstream 6.2 kernel on desktops (M1 Mac Mini, M1 Max/Ultra Mac Studio) and do useful things with it, that is only the case for 16K page size kernel builds. No generic ARM64 distro ships 16K kernels today, to our knowledge.

Our goal is to upstream everything, but that doesn't mean distros instantly get Apple Silicon support. As with many other platforms, there is some integration work required. Distros need to package our userspace tooling and, at this time, offer 16K kernels. In the future, once 4K kernel builds are somewhat usable, you can expect zero-integration distros to somewhat work on these machines (i.e. some hardware will work, but not all, or only partially). This should be sufficient to add a third-party repo with the integration packages.

But for out-of-the-box hardware support, distros will need to work with us to get everything right. We are already working with some, and we expect to announce official Apple Silicon support for a mainstream distro in the near future. Just not quite yet!

An anonymous reader shared this report from InfoWorld: .NET 8, the next planned version of the Microsoft's open source software development platform, is set to emphasize Linux accommodations as well as cloud development and containers.

A first preview of .NET 8 is available for download at dot.microsoft.com for Windows, Linux, and macOS, Microsoft said on February 21. A long-term support (LTS) release that will be supported for three years, .NET 8 is due for production availability in November, a year after the release of predecessor .NET 7.

The new .NET release will be buildable on Linux directly from the dotnet/dotnet repository, using dotnet/source-build to build .NET runtimes, tools, and SDKs. This is the same build used by Red Hat and Canonical to build .NET. Over time, this capability will be extended to support Windows and macOS. Previously, .NET could be built from the source, but a "source tarball" was required from the dotnet/installer.
"We are publishing Ubuntu Chiseled images with .NET 8," adds Microsoft's announcement.

And when it comes to the .NET Monitor tool, "We plan to ship to dotnet/monitor images exclusively as Ubuntu Chiseled, starting with .NET 8. That's notable because the monitor images are the one production app image we publish."

Phoronix reports: While Ubuntu Linux hasn't provided Flatpak support out-of-the-box due to their preference of using their own Snap app packaging/distribution format, Ubuntu flavors/spins have to this point been able to pre-install Flatpak support if they desired. However, for the 23.04 "Lunar Lobster" cycle and moving forward, Ubuntu flavors will no longer be permitted to install Flatpak packages by default.

Flatpak support for Ubuntu and its flavors will remain available in the Ubuntu archive so those wanting to install Flatpak support can easily do so post-install.

This change going into effect with the 23.04 cycle is making it so no Ubuntu flavors will have Flatpak support installed by default / out-of-the-box: they are supposed to center around Debian packages and Snaps for their out-of-the-box packaging support to align with Ubuntu.
From the blog OMG Ubuntu: Ubuntu developers have agreed to stop shipping Flatpak, preinstalled Flatpak apps, and any plugins needed to install Flatpak apps through a GUI software tool in the default package set across all eight of Ubuntu's official flavors, as of the upcoming Ubuntu 23.04 release.

Ubuntu says the decision will 'improve the out-of-the-box Ubuntu experience' for new users by making it clearer about what an "Ubuntu experience" is....

As far as Ubuntu is concerned, only deb and snap software is intrinsic to the 'Ubuntu experience', and that experience now needs to be offered everywhere. Flavor leads (apparently) agree, and have all agreed to mirror regular Ubuntu by not offering Flatpak features in their default install for future releases....

Flatpak will not be uninstalled or removed when user makes the upgrade to Ubuntu 23.04 from a version where Flatpak is already present.

Steven Vaughan-Nichols, writing for ZDNet: Linux 6.2 was released yesterday, and Linus Torvalds described the latest Linux kernel release as, "Maybe it's not a sexy LTS release like 6.1 ended up being, but all those regular pedestrian kernels want some test love too." For once, I disagree with Torvalds. By adding upstream support for the Apple M1 Pro, M1 Max, and M1 Ultra chips, newer Mac owners can look forward to running Linux on their M1-powered machines. And, for techies, that's sexy. Getting Linux to run on the M1 family wasn't easy.

When these high-powered ARM chips first arrived, Torvalds told me in an exclusive interview that he'd like to run Linux on these next-generation Macs. But, while he'd been "waiting for an ARM laptop that can run Linux for a long time," he worried, saying, "The main problem with the M1 for me is the GPU and other devices around it because that's likely what would hold me off using it because it wouldn't have any Linux support unless Apple opens up."

Valentine's Day saw Mozilla releasing version 110.0 of its Firefox browser. OMG Ubuntu highlights some of its new features: Firefox already supports importing bookmarks, history, and passwords from Microsoft Edge, Google Chrome, Chromium, and Safari but once you have the Firefox 110 update you can also import data from Opera, Opera GX, and Vivaldi too — which is handy.

Other changes in Firefox 110 include the ability to clear date, time, and datetime-local input fields using using ctrl + backspace and ctrl + delete on Linux (and Windows) — no, can't say I ever noticed I couldn't do that, either.

Additionally, Mozilla say GPU-accelerated Canvas2D is now enabled by default on Linux, and we can all expect to benefit from a miscellaneous clutch of WebGL performance improvements.

System76 is announcing a "fully redesigned" version of its AMD-only Linux-powered "Pangolin" laptop with an upgraded memory, storage, processor, and display.

9to5Linux reports: It features the AMD Ryzen 7 6800U processor with up to 4.7 GHz clock speeds, 8 cores, 16 threads, and AMD Radeon 680M integrated graphics.... a 15.6-inch 144Hz Full HD (1920 x 1080) display [using 12 integrated Radeon graphics cores] with a matte finish, a sleek magnesium alloy chassis, and promises up to 10 hours of battery life with its 70 Wh Li-Ion battery. It also features a single-color backlit US QWERTY Keyboard and a multitouch clickpad. Under the hood, the Linux-powered laptop boasts 32 GB LPDDR5 6400 MHz of RAM and it can be equipped with up to 16TB PCIe 4.0 NVMe M.2 SSD storage. Another cool feature is the hardware camera kill switch for extra privacy....

As with all of System76's Linux-powered laptops, the all-new Pangolin comes pre-installed with System76's in-house built Pop!_OS Linux distribution featuring the GNOME-based COSMIC desktop and full disk-encryption or with Ubuntu 22.04 LTS.

An anonymous reader quotes a report from ZDNet, written by Jack Wallen: PikaOS is very similar to that of Nobara Linux, which opts for a Fedora base. But what are these two Linux distributions? Simply put, they are Linux for gamers. [...] So, what does PikaOS do that so many other distributions do not? The most obvious thing is that it makes it considerably easier to install the tools needed to play games. Upon first logging in, you're greeted with a Welcome app. In the First Steps tab, you have quick access to tools for updating the system, installing patented codecs and libraries, installing propriety Nvidia drivers, installing apps from the Software Manager, and installing WebApps.

Next comes the Recommended Additions, where you can install the likes of: PikaOS Game Utilities is a meta package that installs Steam, Lutris, GOverlay, MangoHud, Wine, Winetricks, vkBasalt, and other gaming-centric tools; Microsoft TrueType fonts for better Windows font emulation; Blender for creating 3D images; OBS Studio for streaming; Kdenlive for non-linear video editing; Krita for painting; and LibreOffice for productivity. In the Optional Steps tab, you can add AMD proprietary drivers, ROCm drivers, Xone drivers, and Proton GE (for Steam and Wine compatibility). Finally, the Look And Feel tab allows you to customize themes, layouts, and extensions. The layouts section is pretty nifty, as it allows you to configure the GNOME desktop to look and feel like a more traditional desktop, a MacOS-like desktop, a Windows 11 layout, a throwback GNOME 2 desktop, and even a Ubuntu Unity-like desktop.

As far as pre-installed software goes, it's pretty bare bones (until you start adding titles from the Recommended Additions tab in the Welcome App). You'll find Firefox (web browser), Geary (email), Pidgin (messaging), Weather, Calculator, Cheese (web camera software), Rhythmbox, Contacts, a few utilities, and basic games. However, installing new apps is quite simple via the Software Manager app. Of course, the focus of PikaOS is games. When you install the PikaOS Game Utilities, you'll get Steam installed, which makes it easy to play an endless array of games on the Linux desktop. One thing to keep in mind, however, is that when you launch the PikaOS Game Utilities installation, it opens a terminal window to run the installation. Give this plenty of time to complete and, in the end, you can launch Steam, log in to your Steam account, and start playing. Just remember, the first time you launch the Steam app, it will take a moment to update and configure. But once it's up and running... let the games begin.

"From the maintainer of Ubuntu Unity and the Unity desktop environment, here comes blendOS," writes 9to5Linux, "a GNU/Linux distribution that aims to be the last distribution you'll ever use, especially if you distro hop." blendOS is here to offer you "a seamless blend of all Linux distributions," as its creator wants to call it. blendOS is based on Arch Linux and GNOME on Wayland, but it lets you use apps from other popular distributions, such as Fedora Linux or Ubuntu.

This is possible because you can use the native package managers from Arch Linux (pacman — included by default), Fedora Linux (dnf), and Ubuntu (apt), which are included as containers using Distrobox/Podman. However, the DNF and APT package managers aren't included in the live ISO image, nor blendOS's own blend package manager.... It also follows a rolling release model, since it's derived from Arch Linux.

Even if it comes with the GNOME desktop by default on the live ISO image, blendOS will let you deploy a new installation with another popular desktop environment, such as KDE Plasma, MATE, or Xfce, or even window managers like Sway or i3. Apart from the fact that you can install any app from any of the supported Linux distributions, blendOS also comes with out-of-the-box support for sandboxed Flatpak apps, which you can easily install directly from the Flathub Store app, which is a Web App that puts the Flathub website on your desktop.

An anonymous reader shares this report from OMG! Ubuntu: Developers have just uncorked a brand new release of Wine, the open source compatibility layer that allows Windows apps to run on Linux.

A substantial update, Wine 8.0 is fermented from a year's worth of active development (roughly 8,600 changes in total). From that, a wealth of improvements are provided across every part of the Wine experience, from app compatibility, through to performance, and a nicer looking UI....

Notable highlights in Wine 8.0 include the completion of PE conversion, meaning all modules can be built in PE format. Wine devs say this work is an important milestone towards supporting "copy protection, 32-bit applications on 64-bit hosts, Windows debuggers, x86 applications on ARM", and more.

An anonymous reader quotes a report from 9to5Linux: Ubuntu maker Canonical announced Thursday the general availability of its Ubuntu Pro comprehensive subscription for Ubuntu users who want to expand the security updates and compliance of their systems.

First released in a beta version in October 2022 with free subscriptions for personal and small-scale commercial use on up to 5 machines, Ubuntu Pro is only available for Ubuntu LTS (Long-Term Support) releases, starting with Ubuntu 16.04, and promises up to 10 years of security updates, as well as access to exclusive tools. These include Ansible, Apache Tomcat, Apache Zookeeper, Docker, Drupal, Nagios, Node.js, phpMyAdmin, Puppet, PowerDNS, Python 2, Redis, Rust, WordPress, ROS, and many others.

The Ubuntu Pro subscription promises patches for critical CVEs in less than 24 hours and expands the optional technical support to an additional 23,000 open-source packages and toolchains beyond the main operating system, not just for Ubuntu's main software repository....

Canonical says that if you need Ubuntu Pro for more than five PCs, you will have to purchase a paid plan, which is currently priced at $25 USD per year for workstations or $500 USD per year for servers with a 30-day free trial. Official Ubuntu Community members get free support for up to 50 machines.

Last summer GNOME invited people to voluntarily run the tool gnome-info-collect on their systems to send back (non-sensitive/non-identifiable) data about their system configurations. 2,560 people ran the tool, and they're now releasing the data.

Here's the distribution of distros for all 2,560 respondents:

Fedora: 1,376 (54.69%)
Arch: 469 (18.64%)
Ubuntu: 267 (10.61%)
Manjaro: 140 (5.56%)
EndeavourOS: 66 (2.62%)
Debian: 44 (1.75%)
openSUSE: 38 (1.51%)
Pop! 38 (1.51%)
Other: 78 (3.10%)


And the breakdown of hardware manufacturers (top four):

Lenovo: 516 (23.54%)
Dell: 329 (15.01%)
ASUS: 261 (11.91%)
HP: 223 (10.17%)


The site OMG! Linux pointed out that 90% of systems had Flatpak installed — (though it's enabled by default on Fedora, which was 54.69% of all the respondents). Some other interesting stats they noticed: - Most common default browser: Firefox (73.14%), Chrome (11.64%), Brave (4.76%). [Microsoft Edge was the default browser on 37 systems (1.51%) ]

- 83% of users have at least one (non-default) GNOME extension installed
- 'App Indicator' is the most popular extension (by 43% of those using extensions)

- GSConnect, User Themes, and Dash to Panel/Dock also widely used

- Most popular desktop apps: GIMP (58.48%), VLC (53.71%), Steam (53.40%)


[...] The popularity of GNOME extensions will surprise no-one. It is a solid indicator that the existing GNOME extension system is good at doing what it's there to: let users augment and extend their system in the ways they want.
GNOME's report adds that "it's exciting to see the popularity of new GNOME apps like Flatseal, To Do, Bottles, and Fragments."

One other interesting stat from their report: 55% of the participants were using Online Accounts, with Google the most common one added, followed by Nextcloud and Microsoft. But "Some of the account types had very little usage at all, with Foursquare, Facebook, Media Server, Flickr and Last.fm all being active on less than 1% of systems."

OS News cheers the first official release of Vanilla OS, calling it "an immutable desktop Linux distribution that brings some interesting new technologies to the table, such as the Apx package manager."

From the official release announcement: "By default, Apx provides a container based on your Linux distribution (Ubuntu 22.10 for Vanilla OS 22.10) and wraps all commands from the distribution's package manager (apt for Ubuntu). Nevertheless, you can install packages from other package distributions.... Using the --dnf flag with apx will create a new container based on Fedora Linux. Here, apx will manage packages from Fedora's DNF repository, tightly integrating them with the host system.
ZDNet calls Vanilla OS "a new take on Linux that is equal parts heightened security and user-friendly." Among other things, "the developers opted to switch to ABRoot, which allows for fully atomic transactions between 2 root partitions." The official release announcement explains: ABRoot will check which partition is the present root partition (i.e A), then it will mount an overlay on top of it and perform the transaction. If the transaction succeeds, the overlay will be merged with the future root partition (i.e B). On your next boot, the system will automatically switch to the new root partition (B). In case of failure, the overlay will be discarded and the system will boot normally, without any changes to either partition.
But ZDNet explains why this comes in handy: Another really fascinating feature is called Smart Updates, which is enabled in the Vanilla OS Control Center, and ensures the system will not update if it's either under a heavy load or the battery is low. To enable this, open the Vanilla OS Control Center, click on the Updates tab, and then click the ON/OFF slider for SmartUpdate. Once enabled, updates will go through ABRoot transitions and aren't applied until the next reboot. Not only does this allow the updates to happen fully in the background, but it also makes them atomic, so they only proceed when it's guaranteed they will succeed.

The only caveat to this system is that you are limited to either weekly or monthly updates, as there is no daily option for scheduling. However, if you're doing weekly updates, you should be good to go.... Setting aside that which makes Vanilla OS special, the distribution is as stock a GNOME experience as you'll find and does a great job serving as your desktop operating system. It's easy to use, reliable, and performs really well...especially considering this is the first official release.
"Every wallpaper has a light and a dark version," adds the release announcement, "so you can choose the one that best suits your needs."

Long-time Slashdot reader destinyland shares an article listing "the five best Linux distros of 2022" — as chosen by the editor of the blog omg! ubuntu!

"Spoiler: they're not all Ubuntu-based!" the article begins, also noting that it's not a ranking of superiority of importance, but rather "giving a shoutout to some of the year's best Linux releases."

Its top-listed non-Ubuntu distro? Fedora Workstation 37
Fedora Workstation is a flagship desktop Linux distro for good reason: it's robust, it's reliable, it's impeccably produced — it distills what a lot of folks seek most: a "pure" GNOME experience, delivered as devs intend, atop a strong and stable base.

Autumn's offer of Fedora 37 Workstation features GNOME 43 — an update that majorly improves the GNOME Shell user experience with Quick Settings. There's also a more-featured Files rebuilt in GTK4/libadwaita; a revamped Calendar app; a Device Security panel; Raspberry Pi 4 support; GRUB instead of syslinux on BIOS; and more.

Folk often overlook Fedora Workstation because, as Linux distros go, it's rather understated, unassuming, and drama-free. Yet, it is a finessed and functional distro that forgoes fancy flourishes to focus entirely on its performance, its integration, and its cohesion.

If you've never tried Fedora you're missing out, so sort it!
There were two other non-Ubuntu distros on the list:

• Manjaro 22.0 'Sikaris'. "As Arch-based Linux distros go Manjaro is one of the best.... Everything from the shell to the package manager to bespoke touches and apps are cohesive, considered, and choreographed. Manjaro 22.0 isn't just a distro, it's an experience."

• Linux Mint 21. "As well as being easy to use, Linux Mint ships with an interesting selection of pre-installed software that aims to cover most users' needs, including some homegrown apps that are rather special."

The Zero Day Initiative, a zero-day security research firm, announced a new Linux kernel security bug that allows authenticated remote users to disclose sensitive information and run code on vulnerable Linux kernel versions. ZDNet reports: Originally, the Zero Day Initiative ZDI rated it a perfect 10 on the 0 to 10 common Vulnerability Scoring System scale. Now, the hole's "only" a 9.6....

The problem lies in the Linux 5.15 in-kernel Server Message Block (SMB) server, ksmbd. The specific flaw exists within the processing of SMB2_TREE_DISCONNECT commands. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the kernel context. This new program, which was introduced to the kernel in 2021, was developed by Samsung. Its point was to deliver speedy SMB3 file-serving performance....

Any distro using the Linux kernel 5.15 or above is potentially vulnerable. This includes Ubuntu 22.04, and its descendants; Deepin Linux 20.3; and Slackware 15.

"Linux kernel 6.2 should contain fixes for some problems handling floppy disks," reports the Register, "a move which shows that someone somewhere is still using them." This isn't the only such fix in recent years. As a series of articles on Phoronix details, there has been a slow but steady flow of fixes for the kernel's handling of floppy drives since at least kernel 5.17, as The Register mentioned when it came out....

Back in July 2016, SUSE kernel developer Jiri Kosina submitted a patch. The problem arose because this change broke something else and later got reverted, and so the problem hung around. In July last year, he sent in a new patch that fixed it again for the 5.12 kernel, and was later back-ported to 5.10, an LTS version, and again into kernel 5.15 — another an LTS version, and the one you're running today if you're on the current Ubuntu LTS release, or something built from it such as Linux Mint 21....

Now, in December 2022, a new patch for the forthcoming kernel 6.2 fixes a memory leak that dates back to 5.11 or before.
