"Updated kernel packages that fix one security issue and several bugs
are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team 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.

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

This update fixes the following security issue :

* A flaw was found in the way socket buffers (skb) requiring TSO (TCP
segment offloading) were handled by the sfc driver. If the skb did not
fit within the minimum-size of the transmission queue, the network
card could repeatedly reset itself. A remote attacker could use this
flaw to cause a denial of service. (CVE-2012-3412, Important)

Red Hat would like to thank Ben Hutchings of Solarflare (tm) for
reporting this issue.

This update also fixes several bugs. Documentation for these changes
will be available shortly from the Technical Notes document linked to
in the References section.

Users should upgrade to these updated packages, which contain
backported patches to correct this issue, and fix the bugs noted in
the Technical Notes. The system must be rebooted for this update to
take effect."
