It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-25489 in the wild since at least 29 Jun 2023.\n\nAffected product: Samsung 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-2021-25489/ (Markdown: https://insights.sbomify.com/CVE-2021-25489/index.md)","id":"CVE-2021-25489","markdown":"https://insights.sbomify.com/CVE-2021-25489/index.md","name":"CVE-2021-25489","record":{"aliases":["GHSA-hmpv-pvg5-4fpq"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Samsung mobile OS","requires_auth":"low_privilege","summary":"A format string bug in the modem driver allows attackers with radio permissions to cause a kernel panic, requiring a security patch.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"android","vendor":"samsung"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Assuming radio permission is gained, missing input validation in modem interface driver prior to SMR Oct-2021 Release 1 results in format string bug leading to kernel panic.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Samsung Mobile Devices Improper Input Validation","id":"CVE-2021-25489","indexable":true,"kev":{"dateAdded":"2023-06-29","dueDate":"2023-07-20","knownRansomwareCampaignUse":"Unknown","product":"Mobile Devices","requiredAction":"Apply updates per vendor instructions or discontinue use of the product if updates are unavailable","vendorProject":"Samsung","vulnerabilityName":"Samsung Mobile Devices Improper Input Validation Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"samsung:android","products":["samsung:android"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Weak cryptography in Samsung Mobile Devices","id":"CVE-2021-25490"},"packages":[],"prev":{"headline":"Memory corruption in Samsung Mobile Devices","id":"CVE-2021-25488"},"products":["Samsung Mobile Devices"],"published":"2021-10-06","related":[{"cvss_score":8.8,"headline":"Samsung Mobile Devices Out-of-Bounds Write","id":"CVE-2025-21042","kev_date_added":"2025-11-10","published":"2025-09-12"},{"cvss_score":8.8,"headline":"Samsung Mobile Devices Out-of-Bounds Write","id":"CVE-2025-21043","kev_date_added":"2025-10-02","published":"2025-09-12"},{"cvss_score":7.3,"headline":"Samsung Mobile Devices Out-of-Bounds Read","id":"CVE-2021-25487","kev_date_added":"2023-06-29","published":"2021-10-06"},{"cvss_score":6.4,"headline":"Samsung Mobile Devices Race Condition","id":"CVE-2021-25394","kev_date_added":"2023-06-29","published":"2021-06-11"},{"cvss_score":6.4,"headline":"Samsung Mobile Devices Race Condition","id":"CVE-2021-25395","kev_date_added":"2023-06-29","published":"2021-06-11"},{"cvss_score":6.2,"headline":"Samsung Mobile Devices Improper Access Control","id":"CVE-2021-25369","kev_date_added":"2022-11-08","published":"2021-03-26"},{"cvss_score":6.1,"headline":"Samsung Mobile Devices Memory Corruption","id":"CVE-2021-25370","kev_date_added":"2022-11-08","published":"2021-03-26"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Samsung Mobile"]},"summary":"A format string bug in the modem driver allows attackers with radio permissions to cause a kernel panic, requiring a security patch.","url":"https://insights.sbomify.com/CVE-2021-25489/"}
