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-2026-98339 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-2026-98339/ (Markdown: https://insights.sbomify.com/CVE-2026-98339/index.md)","id":"CVE-2026-98339","markdown":"https://insights.sbomify.com/CVE-2026-98339/index.md","name":"CVE-2026-98339","record":{"aliases":["AZL-106101","BELL-CVE-2026-98339","DEBIAN-CVE-2026-98339","GHSA-8rfq-q292-hgch","UBUNTU-CVE-2026-98339"],"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 rogue AP can trigger a kernel warning and potential denial of service in the Linux Wi-Fi subsystem by manipulating BSS type entries during association updates.","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: cfg80211: don't filter by BSS type when removing stale entries\n\nWhen an assoc AP switches to a channel that already has a BSS entry,\ncfg80211_update_assoc_bss_entry() removes that entry before rehashing\nthe real one, since the two would otherwise collide in the BSS rbtree.\n\nThe lookup for that entry also required it to match the connection's BSS\ntype, so an entry advertising e.g. the IBSS capability bit was left in\nplace, and the following cfg80211_rehash_bss() then ran into it:\n\n  WARN_ON(!cmp)\n\nChanging the type shouldn't really happen, but can be triggered by a\nrogue AP/device, so drop the check and remove any entries matching\nthe comparison.","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":"wifi: cfg80211: don't filter by BSS type when removing stale entries","id":"CVE-2026-98339","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"wifi: cfg80211: only group hidden BSSes with beacon entries","id":"CVE-2026-98340"},"packages":[],"prev":{"headline":"wifi: cfg80211: ibss: ref BSS entry for joined event","id":"CVE-2026-98338"},"products":["Linux"],"published":"2026-10-06","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":"2026-10-19","vendors":["Linux"]},"summary":"A rogue AP can trigger a kernel warning and potential denial of service in the Linux Wi-Fi subsystem by manipulating BSS type entries during association updates.","url":"https://insights.sbomify.com/CVE-2026-98339/"}
