CVE-2012-1146

Published: 07 March 2012

The mem_cgroup_usage_unregister_event function in mm/memcontrol.c in the Linux kernel before 3.2.10 does not properly handle multiple events that are attached to the same eventfd, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by registering memory threshold events.

From the Ubuntu security team

A flaw was discovered in the Linux kernel's cgroups subset. A local attacker could use this flaw to crash the system.
