Description Prasad Pandit 2013-04-24 08:44:15 UTC

Linux kernel built with the Bluetooth networking SCO socket support 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.

Upstream fix:
-------------
 -> http://git.kernel.org/linus/c8c499175f7d295ef867335bceb9a76a2c3cdc38
