Affected: Intel(R) Atom and Intel Xeon Scalable Processors

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.

Affected: Ubuntu:Pro:16.04:LTS: intel-microcode, Ubuntu:18.04:LTS: intel-microcode, Ubuntu:20.04:LTS: intel-microcode, Ubuntu:22.04:LTS: intel-microcode

Erik C. Bjorge discovered that some Intel(R) Atom and Intel Xeon Scalable Processors did not properly implement access controls for out-of-band management. This may allow a privileged network-adjacent user to potentially escalate privileges. (CVE-2022-21216)

Cfir Cohen, Erdem Aktas, Felix Wilhelm, James Forshaw, Josh Eads, Nagaraju Kodalapura Nagabhushana Rao, Przemyslaw Duda, Liron Shacham and Ron Anderson discovered that some Intel(R) Xeon(R) Processors used incorrect default permissions in some memory controller configurations when using Intel(R) Software Guard Extensions. This may allow a privileged local user to potentially escalate privileges. (CVE-2022-33196)

It was discovered that some 3rd Generation Intel(R) Xeon(R) Scalable Processors did not properly calculate microkey keying. This may allow a privileged local user to potentially disclose information. (CVE-2022-33972)

Joseph Nuzman discovered that some Intel(R) Processors when using Intel(R) Software Guard Extensions did not properly isolate shared resources. This may allow a privileged local user to potentially disclose information. (CVE-2022-38090)
