Qemu: virtio: unbounded memory allocation on host via guest leading to DoS
The virtqueue_pop function in hw/virtio/virtio.c in QEMU allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion.
Quick Emulator (QEMU) built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement results in unbounded memory allocation on the host controlled by the guest.

CVE-2016-5403 Qemu: virtio: unbounded memory allocation on host via guest leading to DoS
It was found that a malicious guest user could submit more requests than the virtqueue size permits, resulting in a crash of the host QEMU process.
The guest could submit requests without bothering to wait for completion and is therefore not bound by virtqueue size. This requires reusing vring descriptors in more than one request, which is incorrect but possible. Processing a request allocates a VirtQueueElement and therefore causes unbounded memory allocation controlled by the guest.
Exit with an error if the guest provides more requests than the virtqueue size permits. This bounds memory allocation and makes the buggy guest visible to the user.
