Hi,

The following vulnerability was published for libxml2.

CVE-2026-6732[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
