Improper isolation of shared resources in some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5937 advisory.

  - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated     user to potentially enable information disclosure via local access. (CVE-2022-21123)

  - Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)

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

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

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: Buffer overflow due to unbounded strcpy in ISDN I4L driver (CVE-2017-12762)

  - include/linux/init_task.h in the Linux kernel before 2.6.35 does not prevent signals with a process group     ID of zero from reaching the swapper process, which allows local users to cause a denial of service     (system crash) by leveraging access to this process group. (CVE-2010-5328)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

    (CVE-2022-38090)

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.
    (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)
