The version of microcode_ctl installed on the remote host is prior to 2.1-47. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1762 advisory.

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

    A flaw was found in microcode. Under complex microarchitectural conditions, an unexpected code breakpoint     may cause a system hang. The hang was observed on a Skylake server processor, and subsequent analysis     indicated additional potentially affected processors. This flaw allows a possible temporary denial of     service (TDOS) to occur. (CVE-2021-0127)

    Hardware allows activation of test and debug logic at runtime for some Intel(R) processors which may allow     an unauthenticated user to potentially enable escalation of privilege via physical access. (CVE-2021-0146)

    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)

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