In the Linux kernel, the following vulnerability has been resolved:
virtio_net: Fix resize of the RX ring
When a AF_XDP socket is attached, the virtnet_rx_resize
should resize the rq->xsk_buffs XSK buffer array. Otherwise,
when the size grows, the virtnet_rx_resume() causes a write
past the end of the array. This is easily reproducable with
ethtool -G ens3 rx 32
./xdpsock -i eth0 -q 0 -r -z &
ethtool -G eth0 rx 256
