Description Prasad J Pandit 2013-04-24 09:00:51 UTC 
Linux kernel built with the Communication CPU to Application CPU Interface
(CONFIG_CAIF) is vulnerable to an information leakage flaw. It occurs while
receiving messages via recvmsg(2) call.

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