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-2021-25495 in the wild and no public exploit code.\n\nAffected product: Samsung Notes. 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-2021-25495/ (Markdown: https://insights.sbomify.com/CVE-2021-25495/index.md)","id":"CVE-2021-25495","markdown":"https://insights.sbomify.com/CVE-2021-25495/index.md","name":"CVE-2021-25495","record":{"aliases":["GHSA-8xx6-wgwv-844x"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Samsung Notes app","requires_auth":"none","summary":"Heap buffer overflow in Samsung Notes allows arbitrary code execution, requiring users to upgrade the application.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"notes","vendor":"samsung"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A possible heap buffer overflow vulnerability in libSPenBase library of Samsung Notes prior to Samsung Note version 4.3.02.61 allows arbitrary code execution.","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":"Memory corruption in Samsung Notes","id":"CVE-2021-25495","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"samsung:notes","products":["samsung:notes"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Samsung Notes","id":"CVE-2021-25496"},"packages":[],"prev":{"headline":"Memory corruption in Samsung Notes","id":"CVE-2021-25494"},"products":["Samsung Notes"],"published":"2021-10-06","related":[{"cvss_score":8.6,"headline":"Memory corruption in Samsung Notes","id":"CVE-2024-34657","kev_date_added":null,"published":"2024-09-04"},{"cvss_score":7.8,"headline":"Memory corruption in Samsung Notes","id":"CVE-2024-34622","kev_date_added":null,"published":"2024-08-07"},{"cvss_score":7.8,"headline":"Memory corruption in Samsung Notes","id":"CVE-2024-34623","kev_date_added":null,"published":"2024-08-07"},{"cvss_score":7.3,"headline":"Memory corruption in Samsung Notes","id":"CVE-2025-20929","kev_date_added":null,"published":"2025-03-06"},{"cvss_score":7.3,"headline":"Memory corruption in Samsung Notes","id":"CVE-2025-20931","kev_date_added":null,"published":"2025-03-06"},{"cvss_score":7.3,"headline":"Path traversal in Samsung Notes","id":"CVE-2024-34656","kev_date_added":null,"published":"2024-09-04"},{"cvss_score":7.3,"headline":"Memory corruption in Samsung Notes","id":"CVE-2024-34660","kev_date_added":null,"published":"2024-09-04"}],"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":"Heap buffer overflow in Samsung Notes allows arbitrary code execution, requiring users to upgrade the application.","url":"https://insights.sbomify.com/CVE-2021-25495/"}
