It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-21366 and fix it if it is affected.\n\nWhat it is: CVE-2026-21366 is a high-severity vulnerability in Qualcomm Qam8255p Firmware, published on 4 Aug 2026. 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-2026-21366 in the wild and no public exploit code.\n\nAffected product: Qualcomm Qam8255p Firmware. 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-2026-21366/ (Markdown: https://insights.sbomify.com/CVE-2026-21366/index.md)","id":"CVE-2026-21366","markdown":"https://insights.sbomify.com/CVE-2026-21366/index.md","name":"CVE-2026-21366","record":{"aliases":["GHSA-q2v3-gr28-5g2f"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Snapdragon network stack","requires_auth":"low_privilege","summary":"An integer overflow in the Qualcomm Snapdragon network stack allows memory corruption during packet processing, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qualcomm","cpe":[{"product":"lemans_au_lgit_firmware","vendor":"qualcomm"},{"product":"lemansau_firmware","vendor":"qualcomm"},{"product":"qam8255p_firmware","vendor":"qualcomm"},{"product":"qam8295p_firmware","vendor":"qualcomm"},{"product":"qam8620p_firmware","vendor":"qualcomm"},{"product":"qamsrv1h_firmware","vendor":"qualcomm"},{"product":"qamsrv1m_firmware","vendor":"qualcomm"},{"product":"qca6574au_firmware","vendor":"qualcomm"},{"product":"qca6595_firmware","vendor":"qualcomm"},{"product":"qca6595au_firmware","vendor":"qualcomm"},{"product":"qca6688aq_firmware","vendor":"qualcomm"},{"product":"qca6696_firmware","vendor":"qualcomm"},{"product":"qca6698aq_firmware","vendor":"qualcomm"},{"product":"qca6797aq_firmware","vendor":"qualcomm"},{"product":"qca8695au_firmware","vendor":"qualcomm"},{"product":"sa6145p_firmware","vendor":"qualcomm"},{"product":"sa6150p_firmware","vendor":"qualcomm"},{"product":"sa6155p_firmware","vendor":"qualcomm"},{"product":"sa7255p_firmware","vendor":"qualcomm"},{"product":"sa7775p_firmware","vendor":"qualcomm"},{"product":"sa8145p_firmware","vendor":"qualcomm"},{"product":"sa8150p_firmware","vendor":"qualcomm"},{"product":"sa8155p_firmware","vendor":"qualcomm"},{"product":"sa8195p_firmware","vendor":"qualcomm"},{"product":"sa8255p_firmware","vendor":"qualcomm"},{"product":"sa8295p_firmware","vendor":"qualcomm"},{"product":"sa8540p_firmware","vendor":"qualcomm"},{"product":"sa8620p_firmware","vendor":"qualcomm"},{"product":"sa8770p_firmware","vendor":"qualcomm"},{"product":"sa9000p_firmware","vendor":"qualcomm"},{"product":"srv1h_firmware","vendor":"qualcomm"},{"product":"srv1l_firmware","vendor":"qualcomm"},{"product":"srv1m_firmware","vendor":"qualcomm"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Memory corruption while processing a packet with a size close to the maximum allowed value.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Integer Overflow or Wraparound in Data Network Stack \u0026 Connectivity","id":"CVE-2026-21366","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"qualcomm:qam8255p_firmware","products":["qualcomm:qam8255p_firmware","qualcomm:qam8295p_firmware","qualcomm:qam8620p_firmware","qualcomm:qamsrv1h_firmware","qualcomm:qamsrv1m_firmware","qualcomm:qca6574au_firmware","qualcomm:qca6595_firmware","qualcomm:qca6595au_firmware","qualcomm:qca6688aq_firmware","qualcomm:qca6696_firmware","qualcomm:qca6698aq_firmware","qualcomm:qca6797aq_firmware","qualcomm:qca8695au_firmware","qualcomm:sa6145p_firmware","qualcomm:sa6150p_firmware","qualcomm:sa6155p_firmware","qualcomm:sa7255p_firmware","qualcomm:sa7775p_firmware","qualcomm:sa8145p_firmware","qualcomm:sa8150p_firmware","qualcomm:sa8155p_firmware","qualcomm:sa8195p_firmware","qualcomm:sa8255p_firmware","qualcomm:sa8295p_firmware","qualcomm:sa8540p_firmware","qualcomm:sa8620p_firmware","qualcomm:sa8770p_firmware","qualcomm:sa9000p_firmware","qualcomm:srv1h_firmware","qualcomm:srv1l_firmware","qualcomm:srv1m_firmware"],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Buffer Over-read in WLAN Firmware","id":"CVE-2026-21367"},"packages":[],"prev":{"headline":"Substance3D -
