Description Prasad J Pandit 2013-03-08 05:37:25 EST
Linux kernel built with XFRM framework support is vulnerable to a NULL pointer
dereference flaw. It occurs while accessing XFRM state via xfrm_state_netlink
routine.

A privileged(CAP_NET_ADMIN) user/program could use this flaw to crash systems,
resulting in DoS.
