    A microcode update has been released for Intel processors, addressing multiple     vulnerabilties which potentially could cause local privileged escalation or     local DoS.

    CVE-2024-23918

        Improper conditions check in some Intel(R) Xeon(R) processor memory controller         configurations when using Intel(R) SGX may allow a privileged user to         potentially enable escalation of privilege via local access. (INTEL-SA-01079)

    CVE-2024-21853

        Improper finite state machines (FSMs) in the hardware logic in some 4th and 5th         Generation Intel(R) Xeon(R) Processors may allow an authorized user to         potentially enable denial of service via local access. (INTEL-SA-01101)

    CVE-2024-21820

        Incorrect default permissions in some Intel(R) Xeon(R) processor memory         controller configurations when using Intel(R) SGX may allow a privileged user         to potentially enable escalation of privilege via local access.
        (INTEL-SA-01079)

    CVE-2024-23984 (already adressed in a previous upload, this upload adds more processor models.)

        Observable discrepancy in RAPL interface for some Intel(R) Processors may allow         a privileged user to potentially enable information disclosure via local         access.



    For Debian 11 bullseye, this problem has been fixed in version     3.20241112.1~deb11u1.

    We recommend that you upgrade your intel-microcode packages.

    Avraham Shalev and Nagaraju N Kodalapura discovered that some Intel(R) Xeon(R) processors did not properly     restrict access to the memory controller when using Intel(R) SGX. This may allow a local privileged     attacker to further escalate their privileges. (CVE-2024-21820, CVE-2024-23918)

    It was discovered that some 4th and 5th Generation Intel(R) Xeon(R) Processors did not properly implement     finite state machines (FSMs) in hardware logic. THis may allow a local privileged attacker to cause a     denial of service (system crash). (CVE-2024-21853)

    It was discovered that some Intel(R) Processors did not properly restrict access to the Running Average     Power Limit (RAPL) interface. This may allow a local privileged attacker to obtain sensitive information.

Tenable has extracted the preceding description block directly from the SUSE 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 ALAS2023-2024-748 advisory.

    2024-12-05: CVE-2024-21820 was added to this advisory.

    2024-12-05: CVE-2024-21853 was added to this advisory.

    2024-12-05: CVE-2024-23918 was added to this advisory.

    Incorrect default permissions in some Intel(R) Xeon(R) processor memory controller configurations when     using Intel(R) SGX may allow a privileged user to potentially enable escalation of privilege via local     access. (CVE-2024-21820)

    Improper finite state machines (FSMs) in the hardware logic in some 4th and 5th Generation Intel(R)     Xeon(R) Processors may allow an authorized user to potentially enable denial of service via local access.
    (CVE-2024-21853)

    Improper conditions check in some Intel(R) Xeon(R) processor memory controller configurations when using     Intel(R) SGX may allow a privileged user to potentially enable escalation of privilege via local access.
    (CVE-2024-23918)
