CVE-2011-2484 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
