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.
