Description Agostino Sarubbo gentoo-dev 2013-03-07 17:14:19 UTC
From $URL :

A vulnerability has been reported in Linux Kernel, which can be exploited by malicious, local users 
to cause a DoS (Denial of Service).

The vulnerability is caused due to a race condition error within the "install_user_keyrings()" 
function (security/keys/process_keys.c) when the "uid" and "uid-session" are not created and can be 
exploited to dereference a NULL-pointer and cause a crash.

No official solution is currently available.
