It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72397 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-72397/ (Markdown: https://insights.sbomify.com/CVE-2026-72397/index.md)","id":"CVE-2026-72397","markdown":"https://insights.sbomify.com/CVE-2026-72397/index.md","name":"CVE-2026-72397","record":{"aliases":["AZL-96290","BELL-CVE-2026-72397","DEBIAN-CVE-2026-72397","GHSA-xrxg-rjqm-5pr4","UBUNTU-CVE-2026-72397"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel PMBus driver","requires_auth":"low_privilege","summary":"Incorrect voltage encoding in the Linux kernel PMBus driver can cause hardware to receive wrong voltage commands, potentially leading to hardware damage or instability.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: (pmbus/core) honor vrm_version in pmbus_data2reg_vid()\n\npmbus_data2reg_vid() hardcoded the VR11 encoding regardless of the\nvrm_version configured by the driver, while pmbus_reg2data_vid()\nalready switched on it.
