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).

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).
