## Overview

In the Linux kernel, the following vulnerability has been resolved:

veth: manage XDP program pointers during channel resize

veth_set_channels() tears down XDP resources for removed RX queues
without clearing rq->xdp_prog.  If the program is then detached or
replaced, those queues keep the old pointer after bpf_prog_put().
A later channel increase can re-enable NAPI and run the freed program.

  BUG: unable to handle page fault for address: ffffc90000256048
  Oops: Oops: 0000 [#1] SMP KASAN NOPTI
  RIP: veth_xdp_rcv_skb (include/linux/filter.h:779
