Description Prasad Pandit 2013-04-24 10:48:53 UTC

Linux kernel built with the The Transparent Inter Process Communication
(CONFIG_TIPC) 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.
