Description Prasad Pandit 2013-03-08 10:37:25 UTC
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

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