CVE-2019-14835

Description

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernels 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.
