A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path=…/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the programs crash using libxml or other possible undefined behaviors.
The product dereferences a pointer that contains a location for memory that was previously valid, but is no longer valid.
