Updated microcodes for Intel processors, fixing various functional
issues, and at least the following security issues:

Sensitive information accessible by physical probing of JTAG interface
for some Intel(R) Processors with SGX may allow an unprivileged user to
potentially enable information disclosure via physical access
(CVE-2022-0005).

may allow an authenticated user to potentially enable information disclosure
via local access (CVE-2022-21131).

Improper input validation for some Intel(R) Xeon(R) Processors may allow a
privileged user to potentially enable denial of service via local access
(CVE-2022-21136).

Processor optimization removal or modification of security-critical code for
some Intel(R) Processors may allow an authenticated user to potentially enable
information disclosure via local access (CVE-2022-21151).
