I had posted a patch here for restricting module loading requests from
user namespaces as a way to reduce attack surface:

v2: 
https://lore.kernel.org/all/20220815082753.6088-1-vegard.nossum@oracle.com/

v1: 
https://lore.kernel.org/all/20220809185229.28417-1-vegard.nossum@oracle.com/

I'll respond to Serge's comment on the v2 thread.
