Attackers can transmit a crafted OOK radio signal or supply a crafted signal file to crash rtl_433 and corrupt stack memory, enabling control-flow hijacking on builds without stack canaries.","severity":"high","score":7.1,"published":"2026-10-28T02:03:18.083Z","modified":"2026-10-28T16:12:02.323Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/merbanan/rtl_433/issues/3739","https://github.com/merbanan/rtl_433/pull/3740","https://github.com/merbanan/rtl_433/commit/f35183aaf1d2d905d422fd70bcae4eb7349d6186","https://github.com/merbanan/rtl_433/blob/25.12/src/devices/proflame2.c#L46-L95","https://github.com/merbanan/rtl_433","https://www.vulncheck.com/advisories/rtl-433-through-25.12-stack-based-buffer-overflow-via-proflame-2-decoder"],"sources":[{"name":"CVE","id":"CVE-2026-117609","modified":"2026-10-28T16:12:02.323Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-117609"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","score":7.1},{"source":"VulnCheck","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","score":7.1}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T17:55:31.619Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
