Am i correct in my understanding that if I've got a Ryzen CPU running Linux, and assuming I've not gotten hit by this beforehand, I'm safe so long as I don't pull newer microcode packages from the repos?

    This Ars article is better. https://arstechnica.com/security/2026/06/users-cry-foul-after-amd-stripped-memory-crypto-from-its-consumer-cpus/

    It looks like it's from a BIOS update. I'm not sure if the microcode packages will do it too.

    Do you know if you actually had this enabled and working?
