CVE-2011-2484 Information

Description

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.
