CVE-2012-1146 (retired)

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