A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, 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.
