This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the &lt;sch:name path=&#34;...&#34;/&gt; schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program&#39;s crash using libxml or other possible undefined behaviors.</p> <p><strong>Affected:</strong> libxml2, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7 Extended Lifecycle Support, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On, Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Telecommunications Update Service, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions and 36 more</p> <p>A use-after-free vulnerability was found in libxml2.
