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.
