{"id":"UBUNTU-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":"2026-10-28T20:17:46.296951702Z","published":"2026-10-28T03:17:00Z","upstream":["CVE-2026-117609"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-117609"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-117609"},{"type":"REPORT","url":"https://github.com/merbanan/rtl_433/issues/3739"},{"type":"REPORT","url":"https://github.com/merbanan/rtl_433/pull/3740"},{"type":"REPORT","url":"https://github.com/merbanan/rtl_433"},{"type":"REPORT","url":"https://github.com/merbanan/rtl_433/blob/25.12/src/devices/proflame2.c#L46-L95"},{"type":"REPORT","url":"https://github.com/merbanan/rtl_433/commit/f35183aaf1d2d905d422fd70bcae4eb7349d6186"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/rtl-433-through-25.12-stack-based-buffer-overflow-via-proflame-2-decoder"}],"affected":[{"package":{"name":"rtl-433","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["19.08-1","19.08-1build1","19.08-2","20.02-1"],"ecosystem_specific":{"binaries":[{"binary_version":"20.02-1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-117609.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20.11-1","21.05-2","21.05-2build1","21.12-1"],"ecosystem_specific":{"binaries":[{"binary_version":"21.12-1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-117609.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["22.11-1","23.11-1","23.11-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"rtl-433","binary_version":"23.11-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-117609.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.12-1","26.07-1"],"ecosystem_specific":{"binaries":[{"binary_name":"rtl-433","binary_version":"26.07-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-117609.json"}},{"package":{"name":"rtl-433","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rtl-433?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.02-1","25.02-1.1","25.12-1"],"ecosystem_specific":{"binaries":[{"binary_version":"25.12-1","binary_name":"rtl-433"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-117609.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H"},{"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"},{"type":"Ubuntu","score":"medium"}]}
