Description Prasad J Pandit 2013-02-20 14:03:12 EST
Linux kernel built with Extended Verification Module(EVM) on and configured
properly, is vulnerable to a NULL pointer de-reference issue, caused by
accessing extended attribute routines of sockfs inode object.

An unprivileged user/program could use this flaw to crash the Linux kernel,
resulting in DoS.
