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-2026-72003 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-2026-72003/ (Markdown: https://insights.sbomify.com/CVE-2026-72003/index.md)","id":"CVE-2026-72003","markdown":"https://insights.sbomify.com/CVE-2026-72003/index.md","name":"CVE-2026-72003","record":{"aliases":["BELL-CVE-2026-72003","DEBIAN-CVE-2026-72003","GHSA-chrv-c8hf-p9c7","UBUNTU-CVE-2026-72003"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Wi-Fi driver","requires_auth":"none","summary":"A heap overflow in the Linux kernel brcmfmac Wi-Fi driver allows remote attackers to execute code or cause a denial of service via a short authentication frame.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmfmac: cyw: fix heap overflow on a short auth frame\n\nbrcmf_notify_auth_frame_rx() takes the frame length from the firmware\nevent and copies the frame body with the management header offset\nsubtracted:\n\n\tu32 mgmt_frame_len = e-\u003edatalen - sizeof(struct brcmf_rx_mgmt_data);\n\t...\n\tmemcpy(\u0026mgmt_frame-\u003eu, frame,\n\t       mgmt_frame_len - offsetof(struct ieee80211_mgmt, u));\n\nThe only length check is e-\u003edatalen \u003e= sizeof(*rxframe), so mgmt_frame_len\ncan be anything from 0 up. offsetof(struct ieee80211_mgmt, u) is 24.
