Medium: kernel

Issue Overview:

The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification.

Affected Packages:

kernel

Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
