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-2026-43229 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-43229/ (Markdown: https://insights.sbomify.com/CVE-2026-43229/index.md)","id":"CVE-2026-43229","markdown":"https://insights.sbomify.com/CVE-2026-43229/index.md","name":"CVE-2026-43229","record":{"aliases":["BELL-CVE-2026-43229","DEBIAN-CVE-2026-43229","GHSA-7vr5-gjv8-9p58","ROOT-OS-UBUNTU-2404-CVE-2026-43229","UBUNTU-CVE-2026-43229"],"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 race condition in the wave5 media driver causes kernel panics during device removal, leading to denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: chips-media: wave5: Fix device cleanup order to prevent kernel panic\n\nMove video device unregistration to the beginning of the remove function\nto ensure all video operations are stopped before cleaning up the worker\nthread and disabling PM runtime. This prevents hardware register access\nafter the device has been powered down.\n\nIn polling mode, the hrtimer periodically triggers\nwave5_vpu_timer_callback() which queues work to the kthread worker.\nThe worker executes wave5_vpu_irq_work_fn() which reads hardware\nregisters via wave5_vdi_read_register().\n\nThe original cleanup order disabled PM runtime and powered down hardware\nbefore unregistering video devices.
