{"id":"DEBIAN-CVE-2026-117609","details":"rtl_433 through 25.12 contains a stack-based buffer overflow vulnerability in proflame2_mc() that allows nearby attackers to write past a 7-byte stack buffer by sending more than seven valid Manchester-coded words. 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.","modified":"2026-10-29T10:00:17.970987419Z","published":"2026-10-28T03:17:12.607Z","upstream":["CVE-2026-117609"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-117609"}],"affected":[{"package":{"name":"rtl-433","ecosystem":"Debian:12","purl":"pkg:deb/debian/rtl-433?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["22.11+git20230213+ds-1","22.11-1","23.11-1","23.11-2","24.10-1","25.02-1","25.02-1.1","25.12-1","26.07-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-117609.json"}},{"package":{"name":"rtl-433","ecosystem":"Debian:13","purl":"pkg:deb/debian/rtl-433?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.02-1","25.02-1+deb13u1","25.02-1.1","25.12-1","26.07-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-117609.json"}},{"package":{"name":"rtl-433","ecosystem":"Debian:14","purl":"pkg:deb/debian/rtl-433?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.02-1","25.02-1.1","25.12-1","26.07-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-117609.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
