AMD Chip Sinkclose

Security experts identified a decades-old AMD CPU bug. This issue may allow malware to severely infiltrate a computer's memory, making it harder to clean

Hackers might run their own code in System Management Mode, AMD processors' most privileged mode for restricted firmware

AMD's Platform Secure Boot security feature is misapplied, researchers warn that Sinkclose malware infections may be tougher to identify or eliminate following reinstallation

Nation-state hackers and other network intruders should be considered. Okupski says it will stay on your drive even if you delete it

AMD "released mitigation options for EPYC datacenter and Ryzen PC products, with embedded mitigations coming soon," WIRED said

AMD's TClose function remaps other memory to SMRAM locations when activated, making computers compatible with older devices that use the same memory addresses

AMD will delay releasing proof-of-concept code for their Sinkclose vulnerability for a few months to remedy the issue

They argue that AMD and other parties aiming to reduce Sinkclose by saying it is too hard to abuse should not restrict customers from fixing as soon as possible
