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-2023-21517 in the wild and no public exploit code.\n\nAffected product: Samsung Mobile Devices. 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-2023-21517/ (Markdown: https://insights.sbomify.com/CVE-2023-21517/index.md)","id":"CVE-2023-21517","markdown":"https://insights.sbomify.com/CVE-2023-21517/index.md","name":"CVE-2023-21517","record":{"aliases":["GHSA-j3q7-q94g-fmjj"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Samsung mobile devices","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a heap out-of-bound write in the Exynos baseband of Samsung mobile devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"exynos","vendor":"samsung"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Heap out-of-bound write vulnerability in Exynos baseband prior to SMR Jun-2023 Release 1 allows remote attacker to execute arbitrary code.","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 Mobile Devices","id":"CVE-2023-21517","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Samsung SearchWidget","id":"CVE-2023-21518"},"packages":[],"prev":{"headline":"Cross-site scripting in Galaxy Store","id":"CVE-2023-21516"},"products":["Samsung Mobile Devices"],"published":"2023-06-28","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-10835","kev_date_added":null,"published":"2020-03-24"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2020-25054","kev_date_added":null,"published":"2020-08-31"},{"cvss_score":4.6,"headline":"Auth bypass in Samsung Mobile Devices","id":"CVE-2023-21467","kev_date_added":null,"published":"2025-09-03"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-12-04","vendors":["Samsung Mobile"]},"summary":"Remote attackers can execute arbitrary code via a heap out-of-bound write in the Exynos baseband of Samsung mobile devices.","url":"https://insights.sbomify.com/CVE-2023-21517/"}
