I just checked the ASUS site for my X570 motherboard and there is an update mentioning "Mitigate the AMD potential security vulnerabilities for AMD Athlon™ processors and Ryzen™ processors."

Just updated my machine. I'd recommend checking your motherboard's BIOS site for potential updates (if you are comfortable with updating your BIOS).

I don't think there is a fix for zenbleed for consumer hardware yet, only for epyc. this is probably for something else, there was a tpm bug that was fixed recently.

Ah, the BIOS was released like a week ago so I thought it was related. Guess I'll continue to keep a look out.

Really interesting read, I wasn’t aware that silicon could have the same bugs we deal with in programs with traditional code, and serialized oracle fuzzing is really interesting to me!
