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-2023-53997 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-2023-53997/ (Markdown: https://insights.sbomify.com/CVE-2023-53997/index.md)","id":"CVE-2023-53997","markdown":"https://insights.sbomify.com/CVE-2023-53997/index.md","name":"CVE-2023-53997","record":{"aliases":["BELL-CVE-2023-53997","DEBIAN-CVE-2023-53997","GHSA-hjrg-jf9q-4c95","UBUNTU-CVE-2023-53997"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel thermal","requires_auth":"low_privilege","summary":"A double-free vulnerability in the Linux kernel thermal subsystem allows attackers to cause denial of service or potentially execute code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nthermal: of: fix double-free on unregistration\n\nSince commit 3d439b1a2ad3 (\"thermal/core: Alloc-copy-free the thermal\nzone parameters structure\"), thermal_zone_device_register() allocates\na copy of the tzp argument and frees it when unregistering, so\nthermal_of_zone_register() now ends up leaking its original tzp and\ndouble-freeing the tzp copy.
