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-2026-74437 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-2026-74437/ (Markdown: https://insights.sbomify.com/CVE-2026-74437/index.md)","id":"CVE-2026-74437","markdown":"https://insights.sbomify.com/CVE-2026-74437/index.md","name":"CVE-2026-74437","record":{"aliases":["BELL-CVE-2026-74437","DEBIAN-CVE-2026-74437","GHSA-5vf9-4h4x-m5f6","UBUNTU-CVE-2026-74437"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A deadlock in the Linux kernel's uvcvideo driver can cause a denial of service when a UVC camera triggers specific asynchronous control events.","user_interaction":"not_required","vuln_class":"race_condition"},"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: uvcvideo: Fix deadlock if uvc_status_stop is called from async_ctrl.work\n\nIf a UVC camera has an asynchronous control, uvc_status_stop may be\ncalled from async_ctrl.work:\n\nuvc_ctrl_status_event_work()\n    uvc_ctrl_status_event()\n        uvc_ctrl_clear_handle()\n\t    uvc_pm_put()\n\t        uvc_status_put()\n\t\t    uvc_status_stop()\n\t\t        cancel_work_sync()\n\nThis will cause a deadlock, since cancel_work_sync will wait for\nuvc_ctrl_status_event_work to complete before returning.\n\nFix this by returning early from uvc_status_stop if we are currently in\nthe work function. flush_status now remains false until uvc_status_start\nis called again, ensuring that uvc_ctrl_status_event_work won't resubmit\nthe URB.","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: uvcvideo: Fix deadlock if uvc_status_stop is called from async_ctrl.work","id":"CVE-2026-74437","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"crypto: sun4i-ss - Remove insecure and unused rng_alg","id":"CVE-2026-74438"},"packages":[],"prev":{"headline":"rxrpc: serialize kernel accept preallocation with socket teardown","id":"CVE-2026-74436"},"products":["Linux"],"published":"2026-08-15","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":"2026-08-17","vendors":["Linux"]},"summary":"A deadlock in the Linux kernel's uvcvideo driver can cause a denial of service when a UVC camera triggers specific asynchronous control events.","url":"https://insights.sbomify.com/CVE-2026-74437/"}
