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.
This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.
