800813: CVE-2012-1146 kernel: mm: memcg: unregistring of events attached to the same eventfd can lead to oops

The MITRE CVE dictionary describes this issue as:

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.
