Software Security Guidance

This information is designed for developers and systems experts looking to understand potential vulnerabilities and assess risk, with resources and recommendations for building more secure solutions.

Affected Processors: Guidance for Security Issues on Intel® Processors

This table shows the impact of transient execution attacks and select security issues on currently supported Intel products, including recommended mitigation where affected.

Processors that are no longer supported and are not listed in the following table can be found in Support.

This table lists processors by product family. For specific product names, see ark.intel.com. For specific mitigation information, select the associated guidance from Intel that's linked in the table header. Use the scrollbars and table tabs below to view all issues.

Key

Software: Mitigation implemented in software, and software updates needed to enable mitigation

MCU: Mitigation requires microcode update

BIOS: BIOS change needed

Hardware + MCU: Mitigation implemented in hardware; microcode update is also required

Hardware + Software: Mitigation implemented in hardware; software updates required or needed for enablement

MCU + Software: Mitigation requires microcode update; software updates required or needed for enablement

Microcode + BIOS: Mitigation requires microcode update loaded by BIOS

Not Affected: Products not affected or mitigated through hardware; may not include enumeration for security vulnerabilities

No Planned Mitigation: Issue exists but no mitigation planned

Note The latest software can be obtained through operating system or VMM vendors

Footnotes

  1. CPUID 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.
     
  2. Intel recommends ensuring all security mitigations provided by Intel are applied and systems are running the latest firmware/MCU versions available. MCU updates may still be required for enumeration even when processors are not affected. Contact OS/VMM vendors for the latest software updates.
      
    Linux 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: How to Find the Microcode Version Currently Running on your Processor.
      
    For more information on Intel processor numbering, visit: Intel® Processor Names and Numbers.
      
  3. This 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.
      
  4. Options may include: process isolation, masking, speculative load hardening or LFENCE insertion, as well as SYSRET or dedicated type, set FTZ, and DAZ. See Intel guidance for more detail.
      
  5. Software tools for Intel® Software Guard Extensions (Intel® SGX); only if Intel SGX is supported.
     
  6. Intel 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.
     
  7. See Intel Guidance for more information.
     
  8. Intel is not planning mitigations as these products are discontinued or no longer supported.
     
  9. Existing Microarchitectural Data Sampling (MDS) mitigations provided in IPU 2019.1 help mitigate against MMIO; there are no new MMIO-specific MCU mitigations for this processor. Intel recommends applying the latest Intel security mitigations and ensuring systems are running the latest firmware/MCU versions available.
     
  10. There is no change in the IPU 2022.1 MCU for these products. The mitigation uses MDS mitigations provided in IPU 2019.1. Intel recommends applying all security mitigations provided by Intel and ensuring your systems are running the latest firmware/MCU versions available from Intel.
      
  11. These processors are affected because of the impact to Intel SGX. See the Intel Guidance for more information.
