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-2026-98346 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-2026-98346/ (Markdown: https://insights.sbomify.com/CVE-2026-98346/index.md)","id":"CVE-2026-98346","markdown":"https://insights.sbomify.com/CVE-2026-98346/index.md","name":"CVE-2026-98346","record":{"aliases":["BELL-CVE-2026-98346","DEBIAN-CVE-2026-98346","GHSA-36pm-6m6w-jv8x","UBUNTU-CVE-2026-98346"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi","requires_auth":"low_privilege","summary":"A null pointer dereference in the Linux kernel WiFi subsystem allows local attackers to cause a system crash by triggering a specific code path with a netdev-less wireless device.","user_interaction":"not_required","vuln_class":"null_dereference"},"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: cfg80211: don't get the radio mask for netdev-less wdevs\n\ncfg80211_calculate_bi_data() calls rdev_get_radio_mask() with\nwdev-\u003enetdev, which can be NULL and then crashes in mac80211.\n\nTo avoid that, invert the order of checks since wdev-\u003enetdev\nis always valid for beaconing interfaces.","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 get the radio mask for netdev-less wdevs","id":"CVE-2026-98346","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"IB/IPoIB: Avoid restoring OPER_UP after multicast flush","id":"CVE-2026-98347"},"packages":[],"prev":{"headline":"wifi: cfg80211: check IP header size in cfg80211_classify8021d()","id":"CVE-2026-98345"},"products":["Linux"],"published":"2026-10-06","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 null pointer dereference in the Linux kernel WiFi subsystem allows local attackers to cause a system crash by triggering a specific code path with a netdev-less wireless device.","url":"https://insights.sbomify.com/CVE-2026-98346/"}
