Description Prasad J 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.

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

This issue affects the version of the kernel package as shipped with
Red Hat Enterprise Linux 5. Future kernel updates for Red Hat Enterprise Linux 5
may address this issue.
