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-2024-36961 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-36961/ (Markdown: https://insights.sbomify.com/CVE-2024-36961/index.md)","id":"CVE-2024-36961","markdown":"https://insights.sbomify.com/CVE-2024-36961/index.md","name":"CVE-2024-36961","record":{"aliases":["BELL-CVE-2024-36961","DEBIAN-CVE-2024-36961","GHSA-rcqf-hc64-m737","UBUNTU-CVE-2024-36961"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel thermal","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel thermal debugfs code allows a local attacker to trigger a NULL pointer dereference, causing a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nthermal/debugfs: Fix two locking issues with thermal zone debug\n\nWith the current thermal zone locking arrangement in the debugfs code,\nuser space can open the \"mitigations\" file for a thermal zone before\nthe zone's debugfs pointer is set which will result in a NULL pointer\ndereference in tze_seq_start().\n\nMoreover, thermal_debug_tz_remove() is not called under the thermal\nzone lock, so it can run in parallel with the other functions accessing\nthe thermal zone's struct thermal_debugfs object.
