"  - It was found that the Linux kernel's Infiniband
    subsystem did not properly sanitize input parameters
    while registering memory regions from user space via the
    (u)verbs API. A local user with access to a
    /dev/infiniband/uverbsX device could use this flaw to
    crash the system or, potentially, escalate their
    privileges on the system. (CVE-2014-8159, Important)

  - A flaw was found in the way the Linux kernel's splice()
    system call validated its parameters. On certain file
    systems, a local, unprivileged user could use this flaw
    to write past the maximum file size, and thus crash the
    system. (CVE-2014-7822, Moderate)

  - A flaw was found in the way the Linux kernel's netfilter
    subsystem handled generic protocol tracking. As
    demonstrated in the Stream Control Transmission Protocol
    (SCTP) case, a remote attacker could use this flaw to
    bypass intended iptables rule restrictions when the
    associated connection tracking module was not loaded on
    the system. (CVE-2014-8160, Moderate)

  - It was found that the fix for CVE-2014-3601 was
    incomplete: the Linux kernel's kvm_iommu_map_pages()
    function still handled IOMMU mapping failures
    incorrectly. A privileged user in a guest with an
    assigned host device could use this flaw to crash the
    host. (CVE-2014-8369, Moderate)

Bug fixes :

  - The maximum amount of entries in the IPv6 route table
    (net.ipv6.route.max_size) was 4096, and every route
    towards this maximum size limit was counted.
    Communication to more systems was impossible when the
    limit was exceeded. Now, only cached routes are counted,
    which guarantees that the kernel does not run out of
    memory, but the user can now install as many routes as
    the memory allows until the kernel indicates it can no
    longer handle the amount of memory and returns an error
    message.

In addition, the default 'net.ipv6.route.max_size' value has been
increased to 16384 for performance improvement reasons.

  - When the user attempted to scan for an FCOE-served
    Logical Unit Number (LUN), after an initial LUN scan, a
    kernel panic occurred in bnx2fc_init_task. System
    scanning for LUNs is now stable after LUNs have been
    added.

  - Under certain conditions, such as when attempting to
    scan the network for LUNs, a race condition in the
    bnx2fc driver could trigger a kernel panic in
    bnx2fc_init_task. A patch fixing a locking issue that
    caused the race condition has been applied, and scanning
    the network for LUNs no longer leads to a kernel panic.

  - Previously, it was not possible to boot the kernel on
    Xen hypervisor in PVHVM mode if more than 32 vCPUs were
    specified in the guest configuration. Support for more
    than 32 vCPUs has been added, and the kernel now boots
    successfully in the described situation.

  - When the NVMe driver allocated a namespace queue, it
    indicated that it was a request-based driver when it was
    actually a block I/O-based driver. Consequently, when
    NVMe driver was loaded along with a request-based dm
    device, the system could terminate unexpectedly or
    become unresponsive when attempting to access data. The
    NVMe driver no longer sets the QUEUE_FLAG_STACKABLE bit
    when allocating a namespace queue and device- mapper no
    longer perceives NVMe driver as request-based; system
    hangs or crashes no longer occur.

  - If a user attempted to apply an NVRAM firmware update
    when running the tg3 module provided with Scientific
    Linux 6.6 kernels, the update could fail. As a
    consequence, the Network Interface Card (NIC) could stay
    in an unusable state and this could prevent the entire
    system from booting. The tg3 module has been updated to
    correctly apply firmware updates.

  - Support for key sizes of 256 and 192 bits has been added
    to AES-NI."
