Same here.

It returns a fatal error that the module is not found.
All I find when searching is that the module is missing in different
distros and some references to CVE-2022-32250 which doesn't clarify
much:
https://research.nccgroup.com/2022/09/01/settlers-of-netlink-exploiting-a-limited-uaf-in-nf_tables-cve-2022-32250/#rip-control-by-triggering-garbage-collection
I wonder if distros have deliberately removed the module because of the
CVE or if there is something else.
What would you advise?
