CVE-2019-14835

Published: 17 September 2019

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.

From the Ubuntu Security Team

Peter Pi discovered a buffer overflow in the virtio network backend (vhost_net) implementation in the Linux kernel. An attacker in a guest may be able to use this to cause a denial of service (host OS crash) or possibly execute arbitrary code in the host OS.
