The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2022:1728-1 advisory.

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

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

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)

    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)

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

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

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-129 advisory.

    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)

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 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.
