    1. Summary:
    
    Updated kernel packages that fix multiple security issues, several bugs,
    and add one enhancement are now available for Red Hat Enterprise Linux 6.
    
    The Red Hat Security Response Team has rated this update as having
    Important security impact. Common Vulnerability Scoring System (CVSS) base
    scores, which give detailed severity ratings, are available for each
    vulnerability from the CVE links in the References section.

    3. Description:
    
    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.
    
    * A use-after-free flaw was found in the way the ping_init_sock() function
    of the Linux kernel handled the group_info reference counter. A local,
    unprivileged user could use this flaw to crash the system or, potentially,
    escalate their privileges on the system. (CVE-2014-2851, Important)
    
    * A NULL pointer dereference flaw was found in the way the
    futex_wait_requeue_pi() function of the Linux kernel's futex subsystem
    handled the requeuing of certain Priority Inheritance (PI) futexes.
    A local, unprivileged user could use this flaw to crash the system.
    (CVE-2012-6647, Moderate)
    
    * A NULL pointer dereference flaw was found in the rds_ib_laddr_check()
    function in the Linux kernel's implementation of Reliable Datagram Sockets
    (RDS). A local, unprivileged user could use this flaw to crash the system.
    (CVE-2013-7339, Moderate)
    
    * It was found that a remote attacker could use a race condition flaw in
    the ath_tx_aggr_sleep() function to crash the system by creating large
    network traffic on the system's Atheros 9k wireless network adapter.
    (CVE-2014-2672, Moderate)
    
    * A NULL pointer dereference flaw was found in the rds_iw_laddr_check()
    function in the Linux kernel's implementation of Reliable Datagram Sockets
    (RDS). A local, unprivileged user could use this flaw to crash the system.
    (CVE-2014-2678, Moderate)
    
    * A race condition flaw was found in the way the Linux kernel's mac80211
    subsystem implementation handled synchronization between TX and STA wake-up
    code paths. A remote attacker could use this flaw to crash the system.
    (CVE-2014-2706, Moderate)
    
    * An out-of-bounds memory access flaw was found in the Netlink Attribute
    extension of the Berkeley Packet Filter (BPF) interpreter functionality in
    the Linux kernel's networking implementation. A local, unprivileged user
    could use this flaw to crash the system or leak kernel memory to user space
    via a specially crafted socket filter. (CVE-2014-3144, CVE-2014-3145,
    Moderate)
    
    This update also fixes several bugs and adds one enhancement.
    Documentation for these changes will be available shortly from the
    Technical Notes document linked to in the References section.
    
    All kernel users are advised to upgrade to these updated packages, which
    contain backported patches to correct these issues and add this
    enhancement. The system must be rebooted for this update to take effect.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
    https://access.redhat.com/articles/11258
    
    To install kernel packages manually, use "rpm -ivh [package]". Do not use
    "rpm -Uvh" as that will remove the running kernel binaries from your
    system. You may use "rpm -e" to remove old kernels after determining that
    the new kernel functions properly on your system.
    
    5. Bugs fixed (https://bugzilla.redhat.com/):
    
    1079214 - CVE-2013-7339 kernel: net: rds: dereference of a NULL device in rds_ib_laddr_check()
    1083246 - CVE-2014-2672 kernel: ath9k: tid->sched race in ath_tx_aggr_sleep()
    1083274 - CVE-2014-2678 kernel: net: rds: dereference of a NULL device in rds_iw_laddr_check()
    1083512 - CVE-2014-2706 Kernel: net: mac80211: crash dues to AP powersave TX vs. wakeup race
    1086730 - CVE-2014-2851 kernel: net: ping: refcount issue in ping_init_sock() function
    1096775 - CVE-2014-3144 CVE-2014-3145 Kernel: filter: prevent nla extensions to peek beyond the end of the message
    1097746 - CVE-2012-6647 Kernel: futex: forbid uaddr == uaddr2 in futex_wait_requeue_pi()
