"From Red Hat Security Advisory 2012:1174 :

Updated kernel packages that fix one security issue and several bugs
are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having low
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 the Linux kernel's dl2k driver, used by
certain D-Link Gigabit Ethernet adapters, restricted IOCTLs. A local,
unprivileged user could use this flaw to issue potentially harmful
IOCTLs, which could cause Ethernet adapters using the dl2k driver to
malfunction (for example, losing network connectivity).
(CVE-2012-2313, Low)

Red Hat would like to thank Stephan Mueller 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 these issues. The system must be
rebooted for this update to take effect."
