Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-1146 medium priority: Ubuntu including 26 source packages (linux, linux-armadaxp, …), 301 status rows across 16 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): DNE 208, not-affected 50, released 34, ignored 9.
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.
