AMD has begun releasing updates to fix some, but not all, affected chips by the recently discovered security flaw “Sinkclose”. The vulnerability detected by researchers at IOActive It was revealed in a report by With cable last week and is said to affect most AMD processors dating back to 2006. While AMD's security team has been working to patch some of these systems, Tom's Hardware Store reports that the Ryzen 1000, 2000 and 3000 series along with Threadripper 1000 and 2000 will not receive such updates.
The company said Tom's Hardware Store that these are some of the “older products that are outside our software support window.” Newer models and all of AMD’s embedded processors have already received or will receive the patch. The Sinkclose flaw is considered to be a greater risk to governments or other large entities than to the average user, and even then, exploiting it would require deep access to a particular system. But the researchers who found it warned that it could be disastrous if exploited, allowing hackers to run code in the chips’ normally protected system management mode.
