This kernel update is based on the upstream 5.2.16 and fixes at least 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). In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information from kernel stack memory because tos and flags fields are not initialized (CVE-2019-16714) WireGuard has been updated to 0.0.20190913. For other uptstream fixes in this update, see the referenced changelogs.
