The CentOS 7 machine is fully-updated from the Continuous Release (CR) 
repository, which is derived from the recently released RHEL 7.7 
(https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7.1908). If needed, 
I can send the full output of yum list installed.

To summarize:

* Latest "official" CentOS 7 (CentOS 7.1804, derived from RHEL 7.6), 
kernel 3.10.0-957.27.2.el7: WireGuard compiles.

* CentOS 7 with CR repo (will be released as CentOS 7.1908), kernel 
3.10.0-1062.el7: WireGuard does not compile.

The changelog from version 3.10.0-957.27.2.el7 to 3.10.0-1062.el7 is 
shown here: https://access.redhat.com/errata/RHSA-2019:2029

Unfortunately, I cannot replicate this error on other machines since I 
have only one test machine. However, the same bug has been reported e.g. 
in 
https://www.reddit.com/r/WireGuard/comments/cy8nk0/wireguard_module_not_loading_with_centos_7_kernel/

As soon as the CentOS RPM repo will be upgraded to v0.0.20190610, I will 
also test that version.

Cheers,

Dario
