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-2026-21111 in the wild and no public exploit code.\n\nAffected product: Samsung Mobile libsthmbc. 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-2026-21111/ (Markdown: https://insights.sbomify.com/CVE-2026-21111/index.md)","id":"CVE-2026-21111","markdown":"https://insights.sbomify.com/CVE-2026-21111/index.md","name":"CVE-2026-21111","record":{"aliases":["GHSA-x69q-4h23-g7jv"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Samsung Mobile OS","requires_auth":"low_privilege","summary":"Local attackers can exploit an out-of-bounds write in a Samsung mobile library to achieve code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SamsungMobile","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Out-of-bounds write in libsthmbc.so prior to One UI 8.5 allows local attackers to write out-of-bounds memory.","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 libsthmbc","id":"CVE-2026-21111","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Samsung Tips","id":"CVE-2026-21112"},"packages":[],"prev":{"headline":"Memory corruption in libsavscmn.so","id":"CVE-2026-21110"},"products":["libsthmbc"],"published":"2026-09-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["Samsung Mobile"]},"summary":"Local attackers can exploit an out-of-bounds write in a Samsung mobile library to achieve code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-21111/"}
