Description Prasad Pandit 2013-04-23 13:07:59 UTC

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.

Upstream fix:
-------------

Comment 1 Prasad Pandit 2013-04-23 13:18:36 UTC

Statement:

This issue does not affect the version of the kernel package as shipped with
Red Hat Enterprise Linux 5.

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.
