[Qemu-devel] Virtio-net drivers immune to Nethammer?

Hi I'm a privacy distro maintainer investigating the implications of the
newly published nethammer attack [0] on KVM guests particularly the
virtio-net drivers. The summary of the paper is that rowhammer can be
remotely triggered by feeding susceptible* network driver crafted
traffic. This attack can do all kinds of nasty things such as modifying
SSL certs on the victim system.

* Susceptible drivers are those relying on Intel CAT, uncached memory or
the clflush instruction.

My question is, do virtio-net drivers do any of these things?
