If I understand it correctly, the chip has the vulnerability, but the malware would be installed on the motherboard in the form of a bootkit. So getting a used CPU is not a threat, but getting a used motherboard is (and kind of always has been) a risk.

It allows for adulteration of firmware, the CPU has firmware. 🀷

CPU firmware exploits are incredibly rare, if there even are any that exist beyond proof-of-concept. The chances of getting an infected CPU from this is so unlikely it’s practically impossible.

You forget that the CPU has a nanny CPU built in these days.
