"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)

This update also fixes several bugs. 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."
