{"id":"DEBIAN-CVE-2026-6732","details":"A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable.","modified":"2026-09-01T08:47:40.555640188Z","published":"2026-04-23T23:16:16.443Z","upstream":["CVE-2026-6732"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-6732"}],"affected":[{"package":{"name":"libxml2","ecosystem":"Debian:14","purl":"pkg:deb/debian/libxml2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.15.3+dfsg-1"}]}],"versions":["2.12.7+dfsg+really2.9.14-2.1","2.13.1+dfsg-0exp1","2.13.3+dfsg-0exp1","2.13.3+dfsg-0exp2","2.14.1+dfsg-0exp1","2.14.2+dfsg-0exp1","2.14.3+dfsg-0exp1","2.14.3+dfsg-0exp2","2.14.3+dfsg-0exp3","2.14.4+dfsg-0exp1","2.14.5+dfsg-0.1","2.14.5+dfsg-0.2","2.14.5+dfsg-0exp1","2.14.5+dfsg-0exp2","2.14.6+dfsg-0.1","2.15.0+dfsg-0.1","2.15.0+dfsg-0.2","2.15.0+dfsg-0.3","2.15.1+dfsg-0.1","2.15.1+dfsg-0.2","2.15.1+dfsg-0.3","2.15.1+dfsg-0.4","2.15.1+dfsg-0.5","2.15.1+dfsg-1","2.15.1+dfsg-2","2.15.2+dfsg-0.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-6732.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
