CVE-2012-0957

Published: 10 October 2012

The override_release function in kernel/sys.c in the Linux kernel before 3.4.16 allows local users to obtain sensitive information from kernel stack memory via a uname system call in conjunction with a UNAME26 personality.

From the Ubuntu security team

Brad Spengler discovered a flaw in the Linux kernel's uname system call. An unprivileged user could exploit this flaw to read kernel stack memory.
