Description Prasad J Pandit 2013-04-23 09:07:59 EDT
Linux kernel built with Bluetooth networking with RFCOMM protocol support
is vulnerable to an information leakage flaw. This occurs while receiving
messages via recvmsg call.

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

Statement:

This issue does not affect the version of the kernel package as shipped with

This issue affects the versions of Linux kernel as shipped with
Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2. Future kernel updates
for Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2 may address this
issue.
