Well, I might have spoken too soon. As soon as a connection was established
to another wireguard peer (v. 0.0.20180118), the CentOS 7.5 server kernel
panic'd.

Message from syslogd@tun001 at May 10 12:53:12 ...
 kernel:Kernel panic - not syncing: Fatal exception in interrupt

Seeing something along the lines of this in the console output on boot:
[   29.418257] wireguard: loading out-of-tree module taints kernel.
