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-2026-68233 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-2026-68233/ (Markdown: https://insights.sbomify.com/CVE-2026-68233/index.md)","id":"CVE-2026-68233","markdown":"https://insights.sbomify.com/CVE-2026-68233/index.md","name":"CVE-2026-68233","record":{"aliases":["AZL-95135","BELL-CVE-2026-68233","DEBIAN-CVE-2026-68233","GHSA-q3jj-fvxw-r3cf","UBUNTU-CVE-2026-68233"],"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 race condition in the Linux kernel's VC4 DRM driver allows a local attacker to cause a denial of service by triggering a use-after-free during teardown.","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\ndrm/vc4: Shut down BO cache timer before teardown\n\nThe BO cache timer callback schedules time_work, and time_work can rearm\nthe timer through vc4_bo_cache_free_old().\n\nvc4_bo_cache_destroy() deletes the timer and then cancels the work, which\ndoes not break that cycle: the work being cancelled can rearm the timer,\nand the timer then queues work again after teardown.\n\nUse timer_shutdown_sync() instead, so the timer cannot be rearmed and the\ncycle ends with cancel_work_sync().","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":"drm/vc4: Shut down BO cache timer before teardown","id":"CVE-2026-68233","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"drm/amdgpu: fix bo-\u003epin leaking in amdgpu_bo_create_reserved","id":"CVE-2026-68234"},"packages":[],"prev":{"headline":"drm/gpusvm: Fix MM reference leak in drm_gpusvm_range_evict","id":"CVE-2026-68232"},"products":["Linux"],"published":"2026-08-10","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":"2026-10-21","vendors":["Linux"]},"summary":"A race condition in the Linux kernel's VC4 DRM driver allows a local attacker to cause a denial of service by triggering a use-after-free during teardown.","url":"https://insights.sbomify.com/CVE-2026-68233/"}
