  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nvirtio_net: Fix resize of the RX ring\n\nWhen a AF_XDP socket is attached, the virtnet_rx_resize\nshould resize the rq-\u003exsk_buffs XSK buffer array. Otherwise,\nwhen the size grows, the virtnet_rx_resume() causes a write\npast the end of the array. This is easily reproducable with\n\n    ethtool -G ens3 rx 32\n    ./xdpsock -i eth0 -q 0 -r -z \u0026\n    ethtool -G eth0 rx 256",
