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-2018-11840 in the wild and no public exploit code.\n\nAffected product: Google Android. 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-2018-11840/ (Markdown: https://insights.sbomify.com/CVE-2018-11840/index.md)","id":"CVE-2018-11840","markdown":"https://insights.sbomify.com/CVE-2018-11840/index.md","name":"CVE-2018-11840","record":{"aliases":["GHSA-fhpc-4q7r-qhmx"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Qualcomm Android kernel","requires_auth":"low_privilege","summary":"A double-free vulnerability in the WLAN driver allows attackers to potentially execute arbitrary code or escalate privileges on Qualcomm-based Android devices.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qualcomm","cpe":[{"product":"android","vendor":"google"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, while processing the WLAN driver command ioctl a temporary buffer used to construct the reply message may be freed twice.","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":"Use after free in Android for MSM, Firefox OS for MSM, QRD Android","id":"CVE-2018-11840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:android","products":["google:android"],"type":"use_after_free","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2018-11841"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2018-11839"},"products":["Android for MSM, Firefox OS for MSM, QRD Android"],"published":"2018-09-18","related":[{"cvss_score":8.8,"headline":"Google Pixel Improper Authorization","id":"CVE-2026-58704","kev_date_added":"2026-09-16","published":"2026-09-15"},{"cvss_score":8.8,"headline":"Android Runtime Use-After-Free","id":"CVE-2025-48543","kev_date_added":"2025-09-04","published":"2025-09-04"},{"cvss_score":8.8,"headline":"Android Framework Privilege Escalation","id":"CVE-2023-35674","kev_date_added":"2023-09-13","published":"2023-09-11"},{"cvss_score":8.4,"headline":"Android Framework Integer Overflow","id":"CVE-2025-48595","kev_date_added":"2026-06-02","published":"2026-06-01"},{"cvss_score":8.1,"headline":"Android Pixel Privilege Escalation","id":"CVE-2024-32896","kev_date_added":"2024-06-13","published":"2024-06-13"},{"cvss_score":7.8,"headline":"Android Framework Privilege Escalation","id":"CVE-2025-48572","kev_date_added":"2025-12-02","published":"2025-12-08"},{"cvss_score":7.8,"headline":"Android Pixel Privilege Escalation","id":"CVE-2024-29748","kev_date_added":"2024-04-04","published":"2024-04-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Qualcomm, Inc."]},"summary":"A double-free vulnerability in the WLAN driver allows attackers to potentially execute arbitrary code or escalate privileges on Qualcomm-based Android devices.","url":"https://insights.sbomify.com/CVE-2018-11840/"}
