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

This update fixes the following security issues :

  - Numerous reference count leaks were found in the Linux
    kernel's block layer I/O context handling
    implementation. This could allow a local, unprivileged
    user to cause a denial of service. (CVE-2012-0879,
    Moderate)

  - A flaw was found in the Linux kernel's cifs_lookup()
    implementation. POSIX open during lookup should only be
    supported for regular files. When non-regular files (for
    example, a named (FIFO) pipe or other special files) are
    opened on lookup, it could cause a denial of service.
    (CVE-2012-1090, Moderate)

  - It was found that the Linux kernel's register set
    (regset) common infrastructure implementation did not
    check if the required get and set handlers were
    initialized. A local, unprivileged user could use this
    flaw to cause a denial of service by performing a
    register set operation with a ptrace() PTRACE_SETREGSET
    or PTRACE_GETREGSET request. (CVE-2012-1097, Moderate)

This update also fixes several bugs and adds various enhancements. The
system must be rebooted for this update to take effect."
