The version of microcode_ctl installed on the remote host is prior to 2.1-47.40. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2022-1606 advisory.

    2024-05-09: CVE-2021-33117 was added to this advisory.

    Improper access control for some 3rd Generation Intel(R) Xeon(R) Scalable Processors before BIOS version     MR7, may allow a local attacker to potentially enable information disclosure via local access.
    (CVE-2021-33117)

    A flaw was found in hw. Processor optimization removal or modification of security-critical code for some     Intel(R) processors may potentially allow an authenticated user to enable information disclosure via local     access. (CVE-2022-21151)

    A flaw was found in hw. Incomplete cleanup in specific special register write operations for some     Intel Processors may allow an authenticated user to enable information disclosure via local access.
    (CVE-2022-21166)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-070 advisory.

    Sensitive information accessible by physical probing of JTAG interface for some Intel(R) Processors with     SGX may allow an unprivileged user to potentially enable information disclosure via physical access.
    (CVE-2022-0005)

    A flaw was found in hw. Improper access control for some Intel(R) Xeon(R) processors may potentially allow     an authenticated user to enable information disclosure via local access. (CVE-2022-21131)

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5486-1 advisory.

    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)
