I hope you’re being sarcastic because if not you’re delisional to expect ECC ram in a laptop. You’re going to pile up software updates that you should absolutely reboot for long before a comic ray causes a meaningful bit flip. ECC is only worthwhile in servers and is a waste of money otherwise, especially since “pro” for laptop = prosumer device.
If you don’t reboot your laptop in years where ECC matters I’m not sure how to help you.
It seems like based on the (very well written) analysis that this is a way to bypass ssh auth, not something that phones out which would've been even scarier.
My server runs arch w/ a LTS kernel (which sounds dumb on the surface, but was by far the easiest way to do ZFS on Linux that wasn't Ubuntu) and it seems that since I don't have SSH exposed to the outside internet for good reason, and my understanding is Arch never patched shhd to begin with that I and most people who would be in similar situations to me are unaffected.
Still insane that this happened to begin with, and I feel bad for the Archlinux maintainers who are now going to feel more pressure to try to catch things like this.
