Description Prasad J Pandit 2013-03-16 06:35:51 EDT 
Linux kernel built with the Layer Two Tunneling Protocol(L2TP) with IPv6
support is vulnerable to an information leakage flaw. It occurs while
fetching socket name with - getsockname - call.

A user/program could use this flaw to leak kernel memory bytes.
