Vigil@nce: Linux kernel, denial of service of virtio

December 2009 by Marc Jacob

An attacker in a guest KVM/QEMU system can use virtio, in order to
stop the guest system.

Severity: 1/4

Consequences: denial of service of computer

Provenance: user shell

Means of attack: no proof of concept, no attack

Ability of attacker: expert (4/4)

Confidence: confirmed by the editor (5/5)

Diffusion of the vulnerable configuration: high (3/3)

Creation date: 11/12/2009

IMPACTED PRODUCTS

 Linux kernel

DESCRIPTION OF THE VULNERABILITY

The virtio interface of the Linux kernel is used by guest systems
to access to virtualized hardware.

An attacker located in a guest system can send malformed data to
the virtio network interface, in order to generate an error in the
kernel.

An attacker in a guest KVM/QEMU system can thus use virtio, in
order to stop the guest system.
