{"id":"DEBIAN-CVE-2026-89329","details":"A flaw was found in `multipathd`. A local attacker with access to the `multipathd` UNIX control socket can exploit this vulnerability by sending valid commands and then ceasing to read replies. This action can cause the `multipathd` listener thread to block, leading to a Denial of Service (DoS) where legitimate Inter-Process Communication (IPC) operations may hang or time out. This issue does not result in privilege escalation, arbitrary code execution, or impact data confidentiality or integrity.","modified":"2026-09-17T08:47:37.058366397Z","published":"2026-09-11T19:17:47.710Z","upstream":["CVE-2026-89329"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-89329"}],"affected":[{"package":{"name":"multipath-tools","ecosystem":"Debian:12","purl":"pkg:deb/debian/multipath-tools?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.0-1","0.11.1-1","0.11.1-2","0.11.1-3","0.11.1-4","0.12.0-1","0.13.0-1","0.14.3-1","0.14.3-2","0.14.3-3","0.14.3-4","0.15.0-1","0.9.4-10","0.9.4-3","0.9.4-3+deb12u1","0.9.4-3+deb12u2","0.9.4-4","0.9.4-5","0.9.4-6","0.9.4-7","0.9.4-8","0.9.4-9","0.9.7-1","0.9.7-2","0.9.7-3","0.9.7-4","0.9.7-6","0.9.7-7","0.9.8-1","0.9.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-89329.json"}},{"package":{"name":"multipath-tools","ecosystem":"Debian:13","purl":"pkg:deb/debian/multipath-tools?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.11.1-2","0.11.1-3","0.11.1-4","0.12.0-1","0.13.0-1","0.14.3-1","0.14.3-2","0.14.3-3","0.14.3-4","0.15.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-89329.json"}},{"package":{"name":"multipath-tools","ecosystem":"Debian:14","purl":"pkg:deb/debian/multipath-tools?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.11.1-2","0.11.1-3","0.11.1-4","0.12.0-1","0.13.0-1","0.14.3-1","0.14.3-2","0.14.3-3","0.14.3-4","0.15.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-89329.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
