Updated microcode packages fix security vulnerabilities:

Insufficient granularity of access control in out-of-band management in some Intel(R) Atom and Intel Xeon Scalable Processors may allow a privileged user to potentially enable escalation of privilege via adjacent network access (CVE-2022-21216 / intel-sa-00700).

Incorrect default permissions in some memory controller configurations for some Intel(R) Xeon(R) Processors when using Intel(R) Software Guard Extensions which may allow a privileged user to potentially enable escalation of privilege via local access (CVE-2022-33196 / intel-sa-00738).

Incorrect calculation in microcode keying mechanism for some 3rd Generation Intel(R) Xeon(R) Scalable Processors may allow a privileged user to potentially enable information disclosure via local access (CVE-2022-33972 / intel-sa-00730).

Improper isolation of shared resources in some Intel(R) Processors when using Intel(R) Software Guard Extensions may allow a privileged user to potentially enable information disclosure via local access (CVE-2022-38090 / intel-sa-00767).
