(RHSA-2012:1174) Low: kernel security and bug fix update

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.
