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.
