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
