DEBIAN-CVE-2026-6732 PUBLISHED CVSS 7.5 HIGH

Record from OSV · Published April 23, 2026

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.
