Footnotes

1CPUID description: Example CPUID = 906EB. Family = 06 / Extended Model = 9 / Model Number = E / Stepping ID = B. See Intel Software Developer’s Manual Version 071, Volume 2A, Figure 3-6 for reference

2Linux Users: The microcode image is named after the family/model/stepping. You can locate these from /proc/cpuinfo. Example: For Family 06, Model 85, Stepping 4 (values in decimal), the corresponding microcode file is 06-55-04 located in /lib/firmware/intel-ucode/ (values in hexadecimal).
Look at the microcode version number at the official public Intel microcode website. Calculate Family-Model-Stepping before downloading appropriate microcode.
Windows users: Read the version with the following PowerShell command: reg query HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0 /v "Update Revision" .
Or use the Intel® Processor Identification Utility tool to check the microcode version and compare against the latest microcode listed above.

For more information on finding microcode versions, visit: https://www.intel.com/content/www/us/en/support/articles/000055672/processors.html.
For more information on Intel processor numbering, visit: https://www.intel.com/content/www/us/en/processors/processor-numbers.html

3This column describes mitigations for RDMSR at CPL3 and RDMSR in a Virtual Machine Extensions (VMX) guest when the VMM indicates that MSR should cause a VM exit. See the linked Intel Guidance for more details on other aspects of v3a.

4Options include: process isolation, masking, or LFENCE insertion.

5Software tools for Intel® Software Guard Extensions (Intel® SGX); only if Intel SGX is supported.

6Intel is not aware of any real-world impact outside Intel® SGX and is only releasing mitigations for Intel SGX software. Software mitigation outside of Intel SGX may be possible. Please see Intel Guidance for additional information.

7See Intel Guidance for more information.
