Description Prasad J Pandit 2013-12-06 08:29:52 EST 
Linux kernel built with the IPv6 protocol(CONFIG_IPv6) along with the IPv6
source address based routing support(CONFIG_IPV6_SUBTREE) is vulnerable to a
NULL pointer dereference flaw. It could occur while doing an ioctl(SIOCADDRT)
call on an IPv6 socket. User would need to have CAP_NET_ADMIN privileges to
perform such a call.

A user/program with CAP_NET_ADMIN privileges could use this flaw to crash a
system resulting in DoS.
