Intel recommends that users of the affected IntelÂ® products update to the latest BIOS
firmware version provided by the system manufacturer that addresses these issues.
Intel would like to thank Dmitry Frolov for reporting CVE-2020-0528, and an Intel partner for
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.
