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-2021-39658 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-2021-39658/ (Markdown: https://insights.sbomify.com/CVE-2021-39658/index.md)","id":"CVE-2021-39658","markdown":"https://insights.sbomify.com/CVE-2021-39658/index.md","name":"CVE-2021-39658","record":{"aliases":["1732729","A-207479207","ASB-A-207479207","GHSA-vrhh-9qjg-rj58"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Android OS","requires_auth":"none","summary":"Third-party apps can modify system properties via the ismsEx service due to missing permission checks, leading to privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"ismsEx service is a vendor service in unisoc equipment。ismsEx service is an extension of sms system service，but it does not check the permissions of the caller，resulting in permission leaks。Third-party apps can use this service to arbitrarily modify and set system properties。Product: AndroidVersions: Android SoCAndroid ID: A-207479207","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":"Missing authorization in Android","id":"CVE-2021-39658","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:android","products":["google:android"],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Android","id":"CVE-2021-39659"},"packages":[],"prev":{"headline":"Information disclosure in Android","id":"CVE-2021-39657"},"products":["Android"],"published":"2022-02-11","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":"2024-08-04","vendors":["n/a"]},"summary":"Third-party apps can modify system properties via the ismsEx service due to missing permission checks, leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2021-39658/"}
