Description Prasad Pandit 2013-04-24 09:47:51 UTC 
Linux kernel built with Logical Link layer Control(CONFIG_LLC) protocol
support is vulnerable to an information leakage flaw. It occurs while receiving
messages via recvmsg(2) socket call.

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