CVE-2012-6647  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Oracle:5 kernel-uek to version 0:2.6.32-400.36.6.el5uek or higher.
This issue was patched in ELSA-2014-3054.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek package and not the kernel-uek package as distributed by Oracle. See How to fix? for Oracle:5 relevant fixed versions and status.

The futex_wait_requeue_pi function in kernel/futex.c in the Linux kernel before 3.5.1 does not ensure that calls have two different futex addresses, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted FUTEX_WAIT_REQUEUE_PI command.
