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 issue, an Intel SGX TCB Recovery is planned. Details can be found here .

Refer to Intel SGX Attestation Technical Details for more information on the
Intel SGX TCB recovery process.

Further TCB Recovery Guidance for developers is available.

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.
