Advanced Micro releases update on AMD Processor Security 1/11/2018 (12.14 +0.18)
- The public disclosure on January 3rd that multiple research teams had discovered security issues related to how modern microprocessors handle speculative execution has brought to the forefront the constant vigilance needed to protect and secure data. These threats seek to circumvent the microprocessor architecture controls that preserve secure data.
- Google Project Zero (GPZ) Variant 1 (Bounds Check Bypass or Spectre) is applicable to AMD processors. "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."
- GPZ Variant 2 (Branch Target Injection or Spectre) is applicable to AMD processors. "While we believe that AMD's processor architectures make it difficult to exploit Variant 2, we continue to work closely with the industry on this threat. We have defined additional steps through a combination of processor microcode updates and OS patches that we will make available to AMD customers and partners to further mitigate the threat."
- "There have also been questions about GPU architectures. AMD Radeon GPU architectures do not use speculative execution and thus are not susceptible to these threats. We will provide further updates as appropriate on this site as AMD and the industry continue our collaborative work to develop mitigation solutions to protect users
