In case of WireGuard DPKG package being installed, just run: 
dpkg-reconfigure wireguard-dkms

This will rebuild the module for the current and latest installed 
kernel+headers.

In some cases, kernel package updates even automatically trigger the 
rebuild, e.g. on Debian x86 with linux-image-amd64/linux-headers-amd64, 
AFAIK. But this is up to the package maintainers and depend on the 
OS/package system.

Best regards
