Security Fix(es):
    
    * A buffer overflow flaw was found in the way Linux kernel's vhost
    functionality that translates virtqueue buffers to IOVs, logged the buffer
    descriptors during migration. A privileged guest user able to pass
    descriptors with invalid length to the host when migration is underway,
    could use this flaw to increase their privileges on the host.
