"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-1276:01 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any
    Linux operating system.  The kernel handles the basic functions
    of the operating system: memory allocation, process allocation, device
    input and output, etc.
    Security issues fixed with this release:
    CVE-2016-6828
    The tcp_check_send_head function in include/net/tcp.h in the Linux
    kernel before 4.7.5 does not properly maintain certain SACK state
    after a failed data copy, which allows local users to cause a denial
    of service (tcp_xmit_retransmit_queue use-after-free and system crash)
    via a crafted SACK option.
    CVE-2016-7117
    Use-after-free vulnerability in the __sys_recvmmsg function in
    net/socket.c in the Linux kernel before 4.5.2 allows remote attackers
    to execute arbitrary code via vectors involving a recvmmsg system call
    that is mishandled during error processing.
    CVE-2016-9555
    The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux
    kernel before 4.8.8 lacks chunk-length checking for the first chunk,
    which allows remote attackers to cause a denial of service
    (out-of-bounds slab access) or possibly have unspecified other impact
    via crafted SCTP data.
    Fixed bugs:
    * Previously, the performance of Internet Protocol over InfiniBand (IPoIB) was suboptimal due to a
    conflict of IPoIB with the Generic Receive Offload (GRO) infrastructure. With this update, the data cached
    by the IPoIB driver has been moved from a control block into the IPoIB hard header, thus avoiding the GRO
    problem and the corruption of IPoIB address information. As a result, the performance of IPoIB has been
    improved.
    * Previously, when a virtual machine (VM) with PCI-Passthrough interfaces was recreated, a race condition
    between the eventfd daemon and the virqfd daemon occurred. Consequently, the operating system rebooted.
    This update fixes the race condition. As a result, the operating system no longer reboots in the described
    situation.
    * Previously, a packet loss occurred when the team driver in round-robin mode was sending a large number
    of packets. This update fixes counting of the packets in the round-robin runner of the team driver, and
    the packet loss no longer occurs in the described situation.
    * Previously, the virtual network devices contained in the deleted namespace could be deleted in any
    order. If the loopback device was not deleted as the last item, other netns devices, such as vxlan
    devices, could end up with dangling references to the loopback device. Consequently, deleting a network
    namespace (netns) occasionally ended by a kernel oops. With this update, the underlying source code has
    been fixed to ensure the correct order when deleting the virtual network devices on netns deletion. As a
    result, the kernel oops no longer occurs under the described circumstances.
    * Previously, a Kabylake system with a Sunrise Point Platform Controller Hub (PCH) with a PCI device ID of
    0xA149 showed the following warning messages during the boot:
    Unknown Intel PCH (0xa149) detected. Warning: Intel Kabylake processor with unknown PCH - this hardware
    has not undergone testing by Red Hat and might not be certified. Please consult
    https://hardware.redhat.comfor certified hardware.
    * Previously, the operating system occasionally became unresponsive after a long run. This was caused by a
    race condition between the try_to_wake_up() function and a woken up task in the core scheduler. With this
    update, the race condition has been fixed, and the operating system no longer locks up in the described
    scenario.
    These updated kernel packages include several security issues and numerous bug fixes, some of which you
    can see below.
