Hi,
Here are 6 patches that harden console, net and 9p drivers against
various malicious host input as well as close a bounds check bypass
in the split virtio ring.

* CC'ing lkml
Alexander Shishkin (3):
virtio console: Harden control message handling
virtio_net: Guard against buffer length overflow in
xdp_linearize_page()
virtio_ring: Prevent bounds check bypass on descriptor index
Andi Kleen (3):
virtio console: Harden multiport against invalid host input
