{"id":"ALPINE-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":"2026-08-27T22:17:57.481952133Z","published":"2026-04-23T23:16:16.443Z","upstream":["CVE-2026-6732"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-6732"}],"affected":[{"package":{"name":"libxml2","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/libxml2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.13.0"},{"fixed":"2.13.9-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-6732.json"}},{"package":{"name":"libxml2","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/libxml2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.13.0"},{"fixed":"2.13.9-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-6732.json"}},{"package":{"name":"libxml2","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/libxml2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.13.0"},{"fixed":"2.13.9-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-6732.json"}},{"package":{"name":"libxml2","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/libxml2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.13.0"},{"fixed":"2.13.9-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-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"}]}
