Description:	Summary: The remote host is missing an update for the 'intel-microcode' package(s) announced via the USN-5486-1 advisory. Vulnerability Insight: It was discovered that some Intel processors did not implement sufficient control flow management. A local attacker could use this to cause a denial of service. (CVE-2021-0127) Joseph Nuzman discovered that some Intel processors did not properly initialise shared resources. A local attacker could use this to obtain sensitive information. (CVE-2021-0145) Mark Ermolov, Dmitry Sklyarov and Maxim Goryachy discovered that some Intel processors did not prevent test and debug logic from being activated at runtime. A local attacker could use this to escalate privileges. (CVE-2021-0146) It was discovered that some Intel processors did not properly restrict access in some situations. A local attacker could use this to obtain sensitive information. (CVE-2021-33117) Brandon Miller discovered that some Intel processors did not properly restrict access in some situations. A local attacker could use this to obtain sensitive information or a remote attacker could use this to cause a denial of service. (CVE-2021-33120) It was discovered that some Intel processors did not completely perform cleanup actions on multi-core shared buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21123, CVE-2022-21127) Alysa Milburn, Jason Brandt, Avishai Redelman and Nir Lavi discovered that some Intel processors improperly optimised security-critical code. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21151) It was discovered that some Intel processors did not properly perform cleanup during specific special register write operations. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21166) Affected Software/OS: 'intel-microcode' package(s) on Ubuntu 18.04, Ubuntu 20.04, Ubuntu 21.10, Ubuntu 22.04. Solution: Please install the updated package(s).
