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-2023-21511 in the wild and no public exploit code.\n\nAffected product: Samsung Blockchain Keystore. 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-2023-21511/ (Markdown: https://insights.sbomify.com/CVE-2023-21511/index.md)","id":"CVE-2023-21511","markdown":"https://insights.sbomify.com/CVE-2023-21511/index.md","name":"CVE-2023-21511","record":{"aliases":["GHSA-j8ch-x6v3-mfhm"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Samsung Blockchain Keystore","requires_auth":"high_privilege","summary":"A local attacker can read arbitrary memory via an out-of-bounds read in the Samsung Blockchain Keystore trustlet.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"samsung_blockchain_keystore","vendor":"samsung"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Out-of-bounds Read vulnerability while processing CMD_COLDWALLET_BTC_SET_PRV_UTXO in bc_core trustlet from Samsung Blockchain Keystore prior to version 1.3.12.1 allows local attacker to read arbitrary 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":"Information disclosure in Samsung Blockchain Keystore","id":"CVE-2023-21511","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Samsung Mobile Devices","id":"CVE-2023-21512"},"packages":[],"prev":{"headline":"Information disclosure in Samsung Blockchain Keystore","id":"CVE-2023-21510"},"products":["Samsung Blockchain Keystore"],"published":"2023-05-04","related":[{"cvss_score":6.7,"headline":"Memory corruption in Samsung Blockchain Keystore","id":"CVE-2023-21506","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":6.7,"headline":"Memory corruption in Samsung Blockchain Keystore","id":"CVE-2023-21508","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":6.7,"headline":"Memory corruption in Samsung Blockchain Keystore","id":"CVE-2023-21509","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":4.4,"headline":"Information disclosure in Samsung Blockchain Keystore","id":"CVE-2023-21507","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":4.4,"headline":"Information disclosure in Samsung Blockchain Keystore","id":"CVE-2023-21510","kev_date_added":null,"published":"2023-05-04"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-12","vendors":["Samsung Mobile"]},"summary":"A local attacker can read arbitrary memory via an out-of-bounds read in the Samsung Blockchain Keystore trustlet.","url":"https://insights.sbomify.com/CVE-2023-21511/"}
