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-2026-68472 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-2026-68472/ (Markdown: https://insights.sbomify.com/CVE-2026-68472/index.md)","id":"CVE-2026-68472","markdown":"https://insights.sbomify.com/CVE-2026-68472/index.md","name":"CVE-2026-68472","record":{"aliases":["BELL-CVE-2026-68472","DEBIAN-CVE-2026-68472","GHSA-chr6-4qp3-f3h9","UBUNTU-CVE-2026-68472"],"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 malicious access point can cause a kernel crash by sending a malformed EHT multi-link element, requiring a patch to validate element size before reading fields.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: validate EHT MLE before MLD ID read\n\ncfg80211_gen_new_ie() copies ML probe response elements from\nthe parent frame when the parent EHT multi-link element has an\nMLD ID matching the nontransmitted BSSID index.\n\nThe code only checked that the extension element had more than\none byte before calling ieee80211_mle_get_mld_id().
