Tested on Ubuntu 24.04. Security patching from Ubuntu does fix it. Scary vulnerability

It looks like the fix is just disabling the algif_aead kernel module. That prevented the proof of concept script from working on everything I tested it on. Hopefully they will get some kernel updates out soon.

Do the sysctl fix and you’re fine to wait for a patch.
