Title
veth: manage XDP program pointers during channel resize
Summary
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
include/net/xdp.h:696 drivers/net/veth.c:820)
