An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-21504 in the wild and no public exploit code.\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-2023-21504/ (Markdown: https://insights.sbomify.com/CVE-2023-21504/index.md)","id":"CVE-2023-21504","markdown":"https://insights.sbomify.com/CVE-2023-21504/index.md","name":"CVE-2023-21504","record":{"aliases":["GHSA-v49x-2x37-f22g"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Samsung mobile baseband","requires_auth":"none","summary":"Remote attackers can trigger a buffer overflow in the Shannon baseband, causing invalid memory access and potential service disruption or code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"android","vendor":"samsung"}],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Potential buffer overflow vulnerability in mm_Plmncoordination.c in Shannon baseband prior to SMR May-2023 Release 1 allows remote attackers to cause invalid memory access.","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-2023-21504","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"samsung:android","products":["samsung:android"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Samsung Core Service","id":"CVE-2023-21505"},"packages":[],"prev":{"headline":"Memory corruption in Samsung Mobile Devices","id":"CVE-2023-21503"},"products":["Samsung Mobile Devices"],"published":"2023-05-04","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":"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":"Remote attackers can trigger a buffer overflow in the Shannon baseband, causing invalid memory access and potential service disruption or code execution.","url":"https://insights.sbomify.com/CVE-2023-21504/"}
