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-2026-89800 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-2026-89800/ (Markdown: https://insights.sbomify.com/CVE-2026-89800/index.md)","id":"CVE-2026-89800","markdown":"https://insights.sbomify.com/CVE-2026-89800/index.md","name":"CVE-2026-89800","record":{"aliases":["AZL-101622","BELL-CVE-2026-89800","DEBIAN-CVE-2026-89800","GHSA-g7qr-ggg3-47g8","UBUNTU-CVE-2026-89800"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel nouveau driver allows local attackers to cause permanent denial of service by triggering a specific GPU memory unmap failure.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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/nouveau/uvmm: clear the dirty flag when unwinding an OP_UNMAP_SPARSE\n\nA successful OP_UNMAP_SPARSE marks its region dirty with\nnouveau_uvma_region_dirty() and defers the teardown to\nnouveau_uvmm_bind_job_cleanup(); it does not remove the region from\nuvmm-\u003eregion_mt.\n\nIf a later op in the job fails, the unwind path never clears reg-\u003edirty\n(set in one place, cleared nowhere) and sets op-\u003ereg = NULL, so cleanup\nskips the teardown.
