{"id":"CVE-2025-34450","summary":"merbanan/rtl_433 \u003c= 25.02 Stack-based Buffer Overflow","details":"merbanan/rtl_433 versions up to and including 25.02 and prior to commit 25e47f8 contain a stack-based buffer overflow vulnerability in the function parse_rfraw() located in src/rfraw.c. When processing crafted or excessively large raw RF input data, the application may write beyond the bounds of a stack buffer, resulting in memory corruption or a crash. This vulnerability can be exploited to cause a denial of service and, under certain conditions, may be leveraged for further exploitation depending on the execution environment and available mitigations.","modified":"2026-08-12T03:51:41.217068261Z","published":"2025-12-18T21:15:50.730Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/34xxx/CVE-2025-34450.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-121"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/34xxx/CVE-2025-34450.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-34450"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/merbanan-rtl-433-stack-based-buffer-overflow"},{"type":"REPORT","url":"https://github.com/merbanan/rtl_433/issues/3375"},{"type":"FIX","url":"https://github.com/dd32/rtl_433/commit/25e47f8"},{"type":"PACKAGE","url":"https://github.com/merbanan/rtl_433"},{"type":"EVIDENCE","url":"https://github.com/marlinkcyber/advisories/blob/main/advisories/MCSAID-2025-004-rtl_433-rfraw-parse-overflow.md"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dd32/rtl_433","events":[{"introduced":"0"},{"fixed":"25e47f8"}],"database_specific":{"source":"REFERENCES"}},{"type":"GIT","repo":"https://github.com/merbanan/rtl_433","events":[{"introduced":"0"},{"last_affected":"5cae16fbc9c1c98652676ab45d7bbf7f51e6ccea"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"25.02"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:rtl_433_project:rtl_433:*:*:*:*:*:*:*:*"}}],"versions":["25.02","24.10","23.11","22.11","21.12","21.05","20.11","20.02","19.08","18.12","18.05","0.1","0.01"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-34450.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
