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-2025-40197 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-2025-40197/ (Markdown: https://insights.sbomify.com/CVE-2025-40197/index.md)","id":"CVE-2025-40197","markdown":"https://insights.sbomify.com/CVE-2025-40197/index.md","name":"CVE-2025-40197","record":{"aliases":["AZL-70103","BELL-CVE-2025-40197","DEBIAN-CVE-2025-40197","GHSA-qcmj-qqpx-xfgc","ROOT-OS-DEBIAN-11-CVE-2025-40197","ROOT-OS-DEBIAN-13-CVE-2025-40197","UBUNTU-CVE-2025-40197"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel media","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel media subsystem allows local attackers to potentially escalate privileges or cause a system crash.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: mc: Clear minor number before put device\n\nThe device minor should not be cleared after the device is released.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"media: mc: Clear minor number before put device","id":"CVE-2025-40197","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2025"},"n_packages":0,"n_references":8,"next":{"headline":"ext4: avoid potential buffer over-read in parse_apply_sb_mount_options()","id":"CVE-2025-40198"},"packages":[],"prev":{"headline":"fs: quota: create dedicated workqueue for quota_release_work","id":"CVE-2025-40196"},"products":["Linux"],"published":"2025-11-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-23","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel media subsystem allows local attackers to potentially escalate privileges or cause a system crash.","url":"https://insights.sbomify.com/CVE-2025-40197/"}
