USN-5886-1: Intel Microcode vulnerabilities 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. [ more… ]
