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).

Description: Improper access control for some Intel(R) Xeon(R) Processors
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).

For info about the other fixes in this update, see the github reference.");
