AMD has revealed that its chips are also exposed to vulnerabilities exploitable by the Spectre exploit. While arguably not quite as susceptible as Intel’s designs, AMD’s CTO Mark Papermaster has revealed that Google Project Zero Variant 1 (Bounds Check Bypass or Spectre) can affect the company’s silicon. Papermaster said that an operating system patch should be sufficient to nullify the threat.

"We believe this threat can be contained with an operating system (OS) patch and we have been working with OS providers to address this issue,” Papermaster stated. Unfortunately, the first such patch issued by Microsoft this past week bricked some older computers, which Papermaster countered by saying, “We are working closely with [Microsoft] to correct an issue that paused the distribution of patches for some older AMD processors.”

Although AMD’s chips are less vulnerable to the GPZ Variant 2, Papermaster said “AMD’s processor architecture makes it difficult to exploit…” To address this potentiality, AMD is making a series of optional micro code updates available to users who choose to apply it out of an abundance of caution. The first chips to receive these updates will from the Ryzen and EPYC families. Papermaster also indicated that it is working with the Linux community for software fixes coming soon.

I have been writing about consumer technology over the past ten years, previously with the former MacNN and Electronista, and now Notebookcheck since 2017. My first computer was an Apple ][c and this sparked a passion for Apple, but also technology in general. In the past decade, I’ve become increasingly platform agnostic and love to get my hands on and explore as much technology as I can get my hand on. Whether it is Windows, Mac, iOS, Android, Linux, Nintendo, Xbox, or PlayStation, each has plenty to offer and has given me great joy exploring them all. I was drawn to writing about tech because I love learning about the latest devices and also sharing whatever insights my experience can bring to the site and its readership.
