AMD Chips Fail to Receive Critical Sinkclose Security Update

Sunday, 11 August 2024, 20:05

AMD is actively rolling out updates to address the 'Sinkclose' security vulnerability affecting its processors, which dates back to 2006. However, models such as the Ryzen 1000, 2000, and 3000 series, along with Threadripper 1000 and 2000 series, will not receive patches due to being beyond AMD's support window. Although the vulnerability poses a higher risk to large organizations, experts caution that its exploitation could enable unauthorized code execution in critical chip areas.

AMD's Response to Sinkclose Security Flaw

AMD has initiated efforts to patch software for various processors impacted by the recent Sinkclose security flaw, as uncovered by researchers at IOActive. The vulnerability was first detailed in a report by Wired, highlighting that it impacts most AMD processors dating back to 2006.

Older AMD Models Exempt from Updates

Despite the ongoing updates, it has come to light that certain older models, including the Ryzen 1000, 2000, and 3000 series, as well as Threadripper 1000 and 2000 series, will not receive any patches.

  • AMD's rationale: These models are classified as older products and fall outside of the company's software support window.
  • Newer processor models and all embedded processors, however, are set to receive necessary updates.

The Risk of the Sinkclose Flaw

The Sinkclose vulnerability is particularly concerning for governments and larger organizations, as it could allow malicious actors to execute code in the chip's typically secured System Management Mode.

Although the threat level may seem lower for average users, experts advise vigilance, as exploiting the flaw could lead to severe consequences.
