A NULL pointer dereference issue was found in the Floppy disk emulator of QEMU. It could occur while processing read/write ioport commands, if the selected Floppy drive is not initialised with a block device. A privileged guest user could use this flaw to crash the QEMU process on the host resulting in a denial of service scenario.
