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-2026-80677 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-2026-80677/ (Markdown: https://insights.sbomify.com/CVE-2026-80677/index.md)","id":"CVE-2026-80677","markdown":"https://insights.sbomify.com/CVE-2026-80677/index.md","name":"CVE-2026-80677","record":{"aliases":["BELL-CVE-2026-80677","DEBIAN-CVE-2026-80677","GHSA-jprm-rcxh-4jgp","UBUNTU-CVE-2026-80677"],"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":"low_privilege","summary":"A race condition in the Linux kernel driver core allows concurrent unbinding to cause a null pointer dereference, potentially leading to a system crash.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndriver core: use READ_ONCE() for dev-\u003edriver in dev_has_sync_state()\n\ndev_has_sync_state() reads dev-\u003edriver twice without holding\ndevice_lock() -- once for the NULL check and once to dereference\n-\u003esync_state.
