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-2026-98423 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-2026-98423/ (Markdown: https://insights.sbomify.com/CVE-2026-98423/index.md)","id":"CVE-2026-98423","markdown":"https://insights.sbomify.com/CVE-2026-98423/index.md","name":"CVE-2026-98423","record":{"aliases":["AZL-108153","BELL-CVE-2026-98423","DEBIAN-CVE-2026-98423","GHSA-gc6m-v2g5-2jw7","UBUNTU-CVE-2026-98423"],"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":"none","summary":"A race condition in the Linux kernel mac80211_hwsim module allows local attackers to trigger a kernel warning and potential denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211_hwsim: don't hand frames to mac80211 while stopping\n\nThe code checks -\u003estarted for frames coming from wmediumd, but the\nradio can be stopped after the check and before frame delivery,\ncausing mac80211 to hit the WARN_ON(!local-\u003estarted).\n\nExpand the mutex for this case and synchronise against it when the\nradio is stopped to avoid being able to hit the warning with hwsim.\n\nDrop the error print that would've complicated the error path, it\nonly triggers for allocation failures (already noisy) and malformed\nframes anyway.","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: mac80211_hwsim: don't hand frames to mac80211 while stopping","id":"CVE-2026-98423","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"wifi: cfg80211: undo netns switch if renaming the wiphy fails","id":"CVE-2026-98424"},"packages":[],"prev":{"headline":"wifi: mac80211: reset the AP_VLAN tailroom counter on ifdown","id":"CVE-2026-98422"},"products":["Linux"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A race condition in the Linux kernel mac80211_hwsim module allows local attackers to trigger a kernel warning and potential denial of service.","url":"https://insights.sbomify.com/CVE-2026-98423/"}
