CVE-2014-0205

A flaw was found in the way the Linux kernel's futex subsystem handled reference counting when requeuing futexes during futex_wait(). A local, unprivileged user could use this flaw to zero out the reference counter of an inode or an mm struct that backs up the memory area of the futex, which could lead to a use-after-free flaw, resulting in a system crash or, potentially, privilege escalation.

This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG-2.

Future Linux kernel updates for Red Hat Enterprise Linux 6 may address this issue.
