CVE-2011-2484
Published: 24 June 2011
The add_del_listener function in kernel/taskstats.c in the Linux kernel 2.6.39.1 and earlier does not prevent multiple registrations of exit handlers, which allows local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application.
From the Ubuntu security team
Vasiliy Kulikov discovered that taskstats listeners were not correctly handled. A local attacker could expoit this to exhaust memory and CPU resources, leading to a denial of service.
