So I have a 3700x, I've read about the vulnerability but don't fully understand it. How at risk am I?

If an attacker gets access to your system, they will be able to ensure you can't get rid of their access

It will persist across operating system installs

However, this requires them to get access first

Sounds like it's time for an upgrade. Never know what kind of weirdos are out there. Thanks for the information.

If they get root or admin they can hack the chip itself.

But minor exploits, nada, no issue, you good. Gotta get root to make it happen.

Problem is if you, as they say, get got, you have no way of knowing if they're in your CPU, and no way to fix if they did -- basically gotta trash it and replace.

Not particularly. The exploit requires ring 0 access, if an attacker managed to get that, you are screwed already.

[–] lambalicious@lemmy.sdf.org 2 points 3 months ago

Yes.

In short, if you're pwned once, you are pwn3d f0r3v#rrrrreeeheehaahaahaa*cough**cough*

These are the kinds of exploits you use to create APT (Advanced Persistent Threats).
