It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-055 advisory.

    2024-06-06: 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)

    add (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)

    A flaw was found in hw. Improper input validation for some Intel(R) Xeon(R) processors may allow a     privileged user to enable a denial of service via local access. (CVE-2022-21136)

    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. The APIC can operate in xAPIC mode (also known as a legacy mode), in which APIC     configuration registers are exposed through a memory-mapped I/O (MMIO) page. This flaw allows an attacker     who can execute code on a target CPU to query the APIC configuration page. When reading the APIC     configuration page with an unaligned read from the MMIO page, the registers may return stale data from     previous requests made by the same processor core to the same configuration page, leading to unauthorized     access. (CVE-2022-21233)
