CVE-2012-6647

Priority
Medium
Description
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.
Ubuntu-Description
A flaw was discovered in the requeuing of futexes in the Linux kernel. A
local user could exploit this flaw to cause a denial of service (system
crash) or possibly have other unspecified impact.
