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-2026-80722 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-2026-80722/ (Markdown: https://insights.sbomify.com/CVE-2026-80722/index.md)","id":"CVE-2026-80722","markdown":"https://insights.sbomify.com/CVE-2026-80722/index.md","name":"CVE-2026-80722","record":{"aliases":["AZL-98129","BELL-CVE-2026-80722","DEBIAN-CVE-2026-80722","GHSA-h7fr-f2m3-rhpf","UBUNTU-CVE-2026-80722"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Wi-Fi","requires_auth":"none","summary":"A missing validation in the Linux kernel Wi-Fi subsystem allows a remote attacker to cause a denial of service by sending malformed TWT setup frames.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/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\nwifi: mac80211: validate individual TWT params before driver setup\n\nieee80211_process_rx_twt_action() only partially validates a received\nS1G TWT setup frame before queueing it.\n\nAn individual agreement can therefore reach ieee80211_s1g_rx_twt_setup()\nwith twt-\u003elength too short for the full struct ieee80211_twt_params.\n\nThe individual path passes twt to drv_add_twt_setup().
