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-2026-98345 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-2026-98345/ (Markdown: https://insights.sbomify.com/CVE-2026-98345/index.md)","id":"CVE-2026-98345","markdown":"https://insights.sbomify.com/CVE-2026-98345/index.md","name":"CVE-2026-98345","record":{"aliases":["AZL-105990","BELL-CVE-2026-98345","DEBIAN-CVE-2026-98345","GHSA-vm8v-8wgx-pm6r","UBUNTU-CVE-2026-98345"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing IP header size check in the Linux kernel Wi-Fi subsystem allows reading uninitialized memory, potentially disclosing sensitive kernel data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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: check IP header size in cfg80211_classify8021d()\n\nA frame that looks like IP can be transmitted, but be too short, so\nthe DS field is read incorrectly:\n\n  BUG: KMSAN: uninit-value in cfg80211_classify8021d+0x99d/0x12b0 net/wireless/util.c:1027\n   cfg80211_classify8021d+0x99d/0x12b0 net/wireless/util.c:1027\n   ieee80211_select_queue+0x37a/0x9e0 net/mac80211/wme.c:180\n   __ieee80211_subif_start_xmit+0x60f/0x1d90 net/mac80211/tx.c:4304\n   ieee80211_subif_start_xmit+0xa8/0x6d0 net/mac80211/tx.c:4538\n   ...\n   packet_sendmsg+0x9173/0xa2a0 net/packet/af_packet.c:3108\n\nUse skb_header_pointer() like the MPLS case.","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: check IP header size in cfg80211_classify8021d()","id":"CVE-2026-98345","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"wifi: cfg80211: don't get the radio mask for netdev-less wdevs","id":"CVE-2026-98346"},"packages":[],"prev":{"headline":"dmaengine: Fix device kref underflow in dma_chan_put()","id":"CVE-2026-98344"},"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 missing IP header size check in the Linux kernel Wi-Fi subsystem allows reading uninitialized memory, potentially disclosing sensitive kernel data.","url":"https://insights.sbomify.com/CVE-2026-98345/"}
