An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-25477 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-2021-25477/ (Markdown: https://insights.sbomify.com/CVE-2021-25477/index.md)","id":"CVE-2021-25477","markdown":"https://insights.sbomify.com/CVE-2021-25477/index.md","name":"CVE-2021-25477","record":{"aliases":["A-220262213","ASB-A-220262213","GHSA-r436-49p3-g4hr","M-MOLY00684727"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Android mobile device","requires_auth":"high_privilege","summary":"Improper error handling in the MediaTek RRC protocol stack allows remote attackers to cause a modem crash and denial of service on Samsung mobile devices.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"android","vendor":"google"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"An improper error handling in Mediatek RRC Protocol stack prior to SMR Oct-2021 Release 1 allows modem crash and remote denial of service.","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":"Denial of service in Samsung Mobile Devices","id":"CVE-2021-25477","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:android","products":["google:android"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Samsung Mobile Devices","id":"CVE-2021-25478"},"packages":[],"prev":{"headline":"Information disclosure in Samsung Mobile Devices","id":"CVE-2021-25476"},"products":["Samsung Mobile Devices"],"published":"2021-10-06","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":"2024-08-03","vendors":["Samsung Mobile"]},"summary":"Improper error handling in the MediaTek RRC protocol stack allows remote attackers to cause a modem crash and denial of service on Samsung mobile devices.","url":"https://insights.sbomify.com/CVE-2021-25477/"}
