Recommendations:

Intel is releasing prescriptive guidance to address this potential vulnerability and will not be providing additional mitigations for these chipset/SOC products.

  • Ensuring all security mitigations provided by Intel are applied and systems are running the latest firmware version available from Intel.
  • Following standard security practices and preventing unauthorized physical access to systems.
  • Intel recommends users follow existing security best practices and alternate security controls.

Acknowledgements:

This vulnerability was researched and reported by Mark Ermolov and Dmitry Sklyarov (Positive Technologies) and Maxim Goryachy (independent).

 

Intel, and nearly the entire technology industry, follows a disclosure practice called Coordinated Disclosure, under which a cybersecurity vulnerability is generally publicly disclosed only after mitigations are available.
