Original release Jan 03, 2018
Last revised Apr 04, 2018

Summary:

Updated Recommendations Section 04/04/2018

Today a team of security researchers disclosed several software analysis methods that, when used for malicious purposes, have the potential to improperly gather sensitive data from many types of computing devices with many different vendors’ processors and operating systems.

Intel is committed to product and customer security and to responsible disclosure. We worked closely with many other technology companies, including AMD, ARM Holdings and several operating system vendors, to develop an industry-wide approach to mitigate this issue promptly and constructively.

Recommendations: 

Updated 04/04/2018

Intel has worked with operating system vendors, equipment manufacturers, and other ecosystem partners to develop platform firmware and software updates that can help protect systems from these methods.

This includes the release of updated Intel microprocessor microcode to our customers and partners.  Details can be found here: http://newsroom.intel.com/microcode

End users and systems administrators should check with their OEM and system software vendors and apply any available updates as soon as practical.

For non-Intel based systems please contact your system manufacturer or microprocessor vendor (AMD, ARM, Qualcomm, etc.) for updates.

Other variants of this side-channel analysis are being addressed by Operating System and Software Vendors. For more details see:
