AMD Patches Sinkclose Vulnerability for Ryzen 3000 Chips

In a surprising turn of events, AMD has decided to patch the critical Sinkclose vulnerability for its Ryzen 3000 desktop processors, despite previously stating that older chips would not receive the update. This news comes as a relief to many consumers who were left concerned about the security of their systems.

Ryzen 3000 Processors Receive Critical Update

Initially, AMD had announced that newer models of their processors would be patched, leaving those with older models, such as the Ryzen 1000, 2000, and 3000 series, as well as the Threadripper 1000 and 2000 models, at risk. Fortunately, with the new update, Ryzen Threadripper 3000, Threadripper Pro 3000WX, Zen 2 EPYC (7002), Ryzen 3000 mobile, and Ryzen 3000/4000 APUs have now been secured. However, Zen processors continue to be excluded from the patch.

The Danger of Sinkclose

The Sinkclose vulnerability poses a high risk as it allows attackers to execute malicious code inside the System Management Mode (SMM) of AMD processors. This area is reserved for crucial firmware operations, and while no attacks have been reported, the potential danger remains. The update, which was released on August 20, 2024, prevents such exploitation.

As cybersecurity remains a significant concern, users of AMD processors should ensure that their systems are up-to-date with the latest patches to protect their data. While some older models remain without a fix, the latest move by AMD demonstrates their commitment to addressing security flaws and supporting their consumers.

Stay Secure with AMD

With the patch now available for download, users can breathe a sigh of relief and continue to enjoy the high performance of their Ryzen processors without fear of the Sinkclose vulnerability. AMD's decision to reverse course and provide the necessary update highlights the importance of cybersecurity in today's digital age.
