Description Prasad J Pandit 2013-07-05 02:55:30 EDT
Linux kernel built with the IPv6 networking support is vulnerable to an
invalid memory access flaw. It occurs while sending messages using sendmsg(2)
to an IPv4 address over an IPv6 socket. It could result in system crash or
potentially used to gain root privileges.

A user/program could use this flaw to crash the system resulting in DoS.
Nevertheless, potential privilege escalation can not be ruled out.
