Recommendations:

Intel recommends that users of affected Intel® Processors update to the latest version firmware provided by the system manufacturer that addresses these issues. 

Intel has released microcode updates for the affected Intel® Processors that are currently supported on the public github repository. Please see details below on access to the microcode: 

GitHub*: Public Github: https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files

This CVE requires a Microcode Security Version Number (SVN) update. To address this vulnerability, a SGX TCB recovery a SGX TCB-R is planned in Q2 2022.  Refer to Intel® SGX Attestation Technical Details for more information on the SGX TCB recovery process.

Acknowledgements:

The following issue was found internally by Intel employees.  Intel would like to thank Ilya Alexandrovich for reporting this issue.

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.
