NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Ubuntu.
The virtqueue_map_desc function in hw/virtio/virtio.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via a large I/O descriptor buffer length value.
