--- Comment #2 from Teddy Engel <engel.teddy@gmail.com> ---
This was fixed on main by commit 01b0690c49
(https://github.com/freebsd/freebsd-src/commit/01b0690c49) on 4th Oct 2025,
"if_vmx: fix panic during kldload" - which adds the NULL check for sc->vmx_ds
in vmxnet3_update_admin_status(). 

Confirmed it no longer panics on 16.0-CURRENT. The commit has MFC after: 1 week
but doesn't appear to have been merged to stable/14. 

14.3-RELEASE and earlier are still affected.
