Acknowledgements:
The following issues were found internally by Intel employees. Intel would like
to thank William Burton.
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.
