CVE-2019-14821: An out-of-bounds access issue was found in the Linux kernel, all
versions through 5.3, 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-2019-15239: In the Linux kernel, a certain net/ipv4/tcp_output.c change, which
was properly incorporated into 4.16.12, was incorrectly backported to the earlier
longterm kernels, introducing a new vulnerability that was potentially more severe
than the issue that was intended to be fixed by backporting. Specifically, by
adding to a write queue between disconnection and re-connection, a local attacker
can trigger multiple use-after-free conditions. This can result in a kernel crash,
or potentially in privilege escalation.
