An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-39645 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-2021-39645/ (Markdown: https://insights.sbomify.com/CVE-2021-39645/index.md)","id":"CVE-2021-39645","markdown":"https://insights.sbomify.com/CVE-2021-39645/index.md","name":"CVE-2021-39645","record":{"aliases":["A-199805112","GHSA-8xc3-v842-jhxq","PUB-A-199805112"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Android kernel","requires_auth":"none","summary":"A vulnerability exists in the Android kernel, requiring a patch to mitigate potential security risks.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"google_android","cpe":[{"product":"android","vendor":"google"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Product: AndroidVersions: Android kernelAndroid ID: A-199805112References: N/A","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":"Other in Android","id":"CVE-2021-39645","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:android","products":["google:android"],"type":"other","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Other in Android","id":"CVE-2021-39646"},"packages":[],"prev":{"headline":"Other in Android","id":"CVE-2021-39644"},"products":["Android"],"published":"2021-12-15","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A vulnerability exists in the Android kernel, requiring a patch to mitigate potential security risks.","url":"https://insights.sbomify.com/CVE-2021-39645/"}
