Subject: CVE-2020-15469 QEMU: MMIO ops null pointer dereference may lead to

Hello,
A NULL pointer dereference issue was found in various system emulators of
QEMU. It could occur while performing MMIO r/w operations, in case the
respective handler function is not defined. A privileged guest user able to
invoke MMIO operation may use this flaw to crash the QEMU process on the host
resulting in DoS scenario.
