A potential vulnerability in the AMD extension to Linux "hwmon" service may allow an attacker to use the Linux-based Running Average Power Limit (RAPL) interface to show various side channel attacks. In line with industry partners, AMD has updated the RAPL interface to require privileged access.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004176 advisory.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:03545-1 advisory.

    Note this update contains a already fixed references mostly.

    - Remove git-core recommends on SLE to avoid pulling it in unnecessary. (bsc#1250508)

      This feature is mostly intended for developers ('docker build git://') so       most users already have the dependency installed, and the error when git is       missing is fairly straightforward (so they can easily figure out what they       need to install).

    - Include historical changelog data from before the docker-stable fork. The       initial changelog entry did technically provide all the necessary       information, but our CVE tracking tools do not understand how the package is       forked and so it seems that this package does not include fixes for ~12 years       of updates. So, include a copy of the original package's changelog up until       the fork point. bsc#1250596

    - Update to docker-buildx v0.25.0. Upstream changelog:
      <https://github.com/docker/buildx/releases/tag/v0.25.0>

    - Update to Go 1.23 for building now that upstream has switched their 23.0.x       LTSS to use Go 1.23.

    - Do not try to inject SUSEConnect secrets when in Rootless Docker mode, as       Docker does not have permission to access the host zypper credentials in this       mode (and unprivileged users cannot disable the feature using       /etc/docker/suse-secrets-enable.) bsc#1240150

    - Initial docker-stable fork, forked from Docker 24.0.7-ce release       (packaged on 2024-02-14). The original changelog is included below for       historical reference.

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

  - A potential vulnerability in the AMD extension to Linux hwmon service may allow an attacker to use the     Linux-based Running Average Power Limit (RAPL) interface to show various side channel attacks. In line     with industry partners, AMD has updated the RAPL interface to require privileged access. (CVE-2020-12912)

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

  - A potential vulnerability in the AMD extension to Linux hwmon service may allow an attacker to use the     Linux-based Running Average Power Limit (RAPL) interface to show various side channel attacks. In line     with industry partners, AMD has updated the RAPL interface to require privileged access. (CVE-2020-12912)

  - Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2020-8694)

  - Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to     potentially enable information disclosure via local access. (CVE-2020-8695)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4678-1 advisory.

    It was discovered that the AMD Running Average Power Limit (RAPL) driver in the Linux kernel did not     properly restrict access to power data. A local attacker could possibly use this to expose sensitive     information. (CVE-2020-12912)

    Jann Horn discovered that the io_uring subsystem in the Linux kernel did not properly perform reference     counting in some situations. A local attacker could use this to expose sensitive information or possibly     escalate privileges. (CVE-2020-29534)
