It's always fearmongering when it comes to "vulnerabilities" that affect the model of locking down computing devices.
This shit used to confuse me so hard when I was learning security. It seemed that articles were talking about something really important, but I just couldn't connect it to anything I knew. Then I realized they weren't talking about security for users, but rather security from users - and for entities ultimately looking to restrict users (the same inversion-of-authority as TSA propaganda). Hence the syndrome of acronym hell, as that amount of overabstraction is required to motivate a system for its own purposes.
Now given that this is a network exploit, you've got to adapt my model a bit from above - my framing is most clear when talking about local "exploits" in locked down bootloaders etc. But from an individual security perspective here? If you've disabled the network stack in your BIOS (because why the hell is it there in the first place), OR put any management interfaces on their own network unreachable from anything that isn't trusted to be managing, this is an utter nothingburger.
