Holy shit!

A Grey Hat hacker gave AMD unknown months to make a chip patch, then AMD this week clumsily leaked exploit details to China, Russia, and people like me. AMD/Microsoft/Linux solution this morning is to cripple all chips, and buy new 2024 chips later! :

CVE-2023-20569 : https://cve.mitre.org/cgi-bin/cvename.cgi?name=2023-20569

Zen,Zen2, Zen3, Zen4 are this morning all screwed, but Zen 1 fixed with simple 0/1 cpu divide every interrupt, not checking EVERY DIVIDE.

The big story is that for months this exploit has left all AMD servers vulnerable due to painful lack of OK solution.

🚨PCs worldwide after 2023.08.16 patching, are about to get dramatically slower.🚨

AMD SALES DEPARTMENT for 2024 products is pleased by the chip bug.
