Synopsis:          Important: kernel security update
Advisory ID:       RHSA-2015:0919-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2015-0919.html
Issue date:        2015-04-30
CVE Names:         CVE-2014-8159 
=====================================================================

1. Summary:

Updated kernel packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.6 Long Life.

Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux LL (v. 5.6 server) - i386, ia64, noarch, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* It was found that the Linux kernel's Infiniband subsystem did not
properly sanitize input parameters while registering memory regions from
user space via the (u)verbs API. A local user with access to a
/dev/infiniband/uverbsX device could use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2014-8159,
Important)

Red Hat would like to thank Mellanox for reporting this issue.

All kernel users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. The system must be
rebooted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
