Updated microcode packages fix security vulnerabilities: Insufficient granularity of access control in out-of-band management in some Intel® 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® Xeon® Processors when using Intel® 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® Xeon® 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® Processors when using Intel® Software Guard Extensions may allow a privileged user to potentially enable information disclosure via local access (CVE-2022-38090 / intel-sa-00767).
