{"id":"DEBIAN-CVE-2026-80186","details":"A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code execution.","modified":"2026-09-14T17:03:35.577626665Z","published":"2026-08-25T22:17:07.587Z","upstream":["CVE-2026-80186"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-80186"}],"affected":[{"package":{"name":"bluez","ecosystem":"Debian:12","purl":"pkg:deb/debian/bluez?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.66-1","5.66-1+deb12u1","5.66-1+deb12u2","5.68-1","5.68-2","5.69-1","5.70-1","5.70-1.1","5.70-1.1~exp0","5.71-1","5.73-1","5.73-1.1","5.77-1","5.79-1","5.79-2","5.82-1","5.82-1.1","5.83-1","5.83-1~exp1","5.84-1","5.85-1","5.85-2","5.85-3","5.85-4","5.87-1","5.87-2","5.87-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-80186.json"}},{"package":{"name":"bluez","ecosystem":"Debian:13","purl":"pkg:deb/debian/bluez?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.82-1.1","5.83-1","5.83-1~exp1","5.84-1","5.85-1","5.85-2","5.85-3","5.85-4","5.87-1","5.87-2","5.87-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-80186.json"}},{"package":{"name":"bluez","ecosystem":"Debian:14","purl":"pkg:deb/debian/bluez?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.87-3"}]}],"versions":["5.82-1.1","5.83-1","5.83-1~exp1","5.84-1","5.85-1","5.85-2","5.85-3","5.85-4","5.87-1","5.87-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-80186.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}]}
