My personal suggestion would be to add initcall_blacklist=algif_aead_init to your kernel arguments. Ebpf is cool, but not a very trivial solution.

I understand the suggestion might apply to a random, unspecified distro but I disapprove of both the exploit authors and the general Internet suggesting fixes that don't apply to every distro (including copy.fail's AI slop RHEL distro that doesn't exist) without caveating it.

The kernel module blacklist won't work for every situation, if you're not being specific in telling people where it applies, it's best to suggest a solution that actually works regardless of distro or explain how to validate when it applies but nobody is doing that.

Giving a better solution is certainly useful.

I'd used initcall_debug before, but not initcall_blacklist
