Bug Description

I've hit this panic a few times today on focal, 5.4.0-84-generic with wireguard-dkms 1.0.20201112-1~20.04.1

__stack_chk_fail
__icmp_send
wg_xmit
(see panic.jpg for the rest of it)

It looks a lot like https://www.spinics.net/lists/netdev/msg723248.html fixed in
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireguard?id=99fff5264e7ab06f45b0ad60243475be0a8d0559

Does wireguard-dkms need updating with those, or is using a HWE kernel the way to go?
