msm1267 writes: A patch for a critical Linux kernel flaw, present in the code since 2012, is expected to be pushed out today. The vulnerability affects versions 3.8 and higher, said researchers at startup Perception Point who discovered the vulnerability. The flaw also extends to two-thirds of Android devices, the company added. An attacker would require local access to exploit the vulnerability on a Linux server. A malicious mobile app would get the job done on an Android device. The vulnerability is a reference leak that lives in the keyring facility built into the various flavors of Linux. The keyring encrypts and stores login information, encryption keys and certificates, and makes them available to applications. Here's Perception Point's explanation of the problem.
