Description Prasad Pandit 2013-04-24 09:24:20 UTC 
Linux kernel built with the inter-user communication under VM or VIF
(CONFIG_IUCV) 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.
