CVE-2011-2484: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 2.6.39.1
