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.","epss":{"date":"2026-11-01","percentile":0.50305,"score":0.00632},"exploits":[],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793582716407,"publishedAt":1776982774322,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:11503"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-6732"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2461300"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/libxml2/-/issues/1097"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/libxml2/-/merge_requests/411"}],"remediation":[],"revision":"d235d88e942f48b21f82c7b83ebc3d71a2610db060432cf6c0665dc149b924ba","sources":[{"modifiedAt":1793582716407,"name":"CNA: redhat","retrievedAt":1793585309964,"url":"https://www.cve.org/CVERecord?id=CVE-2026-6732"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793585311089,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-6732"}],"ssvc":{"assessedAt":1777027980163,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Libxml2: libxml2: denial of service via crafted xsd-validated document","updatedAt":1793585311089}
