Descriptions
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.
Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host.
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. In the worst case (and likely most common virtualization) scenario this flaw affects KVM/qemu hypervisor enabled hosts running Linux guests.
