Description OSIDB Bzimport 2025-06-12 00:26:13 UTC 
A Heap Use After Free (UAF) vulnerability was discovered in the Schematron in the libxml2. The issue arises in the xmlSchematronGetNode function when processing XPath expressions in Schematron schema elements <sch:name path="..."/>, where a pointer to freed memory is returned and then accessed, leading to undefined behavior and potential crashes.
