An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-80694 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-2026-80694/ (Markdown: https://insights.sbomify.com/CVE-2026-80694/index.md)","id":"CVE-2026-80694","markdown":"https://insights.sbomify.com/CVE-2026-80694/index.md","name":"CVE-2026-80694","record":{"aliases":["AZL-98066","BELL-CVE-2026-80694","DEBIAN-CVE-2026-80694","GHSA-55j9-p2qj-gvrc","UBUNTU-CVE-2026-80694"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A null pointer dereference in the MediaTek Ethernet driver causes a kernel crash when polling is enabled, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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\nnet: ethernet: mtk_eth_soc: pass eth to mtk_handle_irq_rx in poll_controller\n\nmtk_handle_irq_rx expects a struct mtk_eth * (matching the request_irq\ncookie), but mtk_poll_controller incorrectly passed the net_device *.\nCalling ndo_poll_controller with CONFIG_NET_POLL_CONTROLLER enabled\nwould then crash.","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":"net: ethernet: mtk_eth_soc: pass eth to mtk_handle_irq_rx in poll_controller","id":"CVE-2026-80694","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"hwmon: (sht3x) Fix unaligned accesses","id":"CVE-2026-80695"},"packages":[],"prev":{"headline":"idpf: bound interrupt-vector register fill to the allocated array","id":"CVE-2026-80693"},"products":["Linux"],"published":"2026-08-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A null pointer dereference in the MediaTek Ethernet driver causes a kernel crash when polling is enabled, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-80694/"}
