This isn't WireGuard, actually. It's a line in wg-quick's bash that says `ip rule add ... suppress_prefix ...`.
You can reproduce the kernel crash without WireGuard anywhere in the equation with this sequence: ip netns add crash ip -n crash link add dummy1 type dummy ip -n crash link set dummy1 up ip -n crash -6 route add default dev dummy1 ip -n crash -6 rule add table main suppress_prefixlength 0 ip netns exec crash ping -f -c 1000 -W 1 1234::1 || true ip -n crash -6 rule del table main suppress_prefixlength 0 ip -n crash link del dummy1 ip netns del crash I submitted a patch for this upstream here: https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=ca7a03c4175366a92cee0ccc4fec0038c3266e26 It's been backported to stable already. Update your kernel to 5.3.4 and things should work again for you.
