Acknowledgements:
The following issue was found internally by Intel employees. Intel would like
to thank Thierry Fernandes Faria and Chun Feng.
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.
