• Platforms based on Ivy Bridge, Bay Trail and Haswell do not have full mitigations at this time for the Windows* OS. Updating the drivers for these platforms per the recommendation below will substantively reduce the potential attack surface. Intel is working on full mitigations for these platforms and will make them available once they are validated. Linux mitigation for these platforms will be provided for the mainline kernel.

Recommendations:

Intel recommends updating Intel® Processor Graphics Driver for Windows* and the i915 Linux Driver to the latest version (see provided table).

Windows Operating System Driver version*

• 26.20.100.7209 or higher
• 15.45.x.5077 or higher
• 15.40.x.5107 or higher
• 15.36.x.5117 or higher
• 15.33.x.5100 or higher

Updates are available for download at this location: <https://downloadcenter.intel.com/product/80939/Graphics-Drivers&gt;

Linux Operating System

Linux mitigation is targeted to be available on or after January 14, 2020. Kernel version information is targeted to be available January 7, 2020.

Kernel version

• Mainline: 5.5-rc6 or later

• Stable: 5.4.12 or later

• LTS: 4.19.96 or later

• LTS: 4.14.165 or later

• LTS: 4.9.210 or later

• LTS: 4.4.210 or later
