    This kernel update is based on the upstream 5.2.16 and fixes atleast
    the following security issues:
    
    There is heap-based buffer overflow in the marvell wifi chip driver that
    allows local users to cause a denial of service(system crash) or possibly
    execute arbitrary code (CVE-2019-14814, CVE-2019-14815, CVE-2019-14816).
    
    An out-of-bounds access issue was found in the way Linux kernel's KVM
    hypervisor implements the Coalesced MMIO write operation. It operates on
    an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write
    indices 'ring->first' and 'ring->last' value could be supplied by a host
    user-space process. An unprivileged host user or process with access to
    '/dev/kvm' device could use this flaw to crash the host kernel, resulting
    in a denial of service or potentially escalating privileges on the system
    (CVE-2019-14821).
    
    A buffer overflow flaw was found in the way Linux kernel's vhost
    functionality that translates virtqueue buffers to IOVs, logged the buffer
    descriptors during migration. A privileged guest user able to pass
    descriptors with invalid length to the host when migration is underway,
    could use this flaw to increase their privileges on the host
    (CVE-2019-14835).
    
    WireGuard has been updated to 0.0.20190913.
    
    For other uptstream fixes in this update, see the referenced changelogs.
