CVE-2025-11731Network attack vector

Application crash via document-node type confusion

Published Oct 14, 2025 · Updated Oct 14, 2025

Type confusion in libxslt on affected Red Hat platforms allows remote attackers to crash applications via a crafted XSL stylesheet. exsltFuncResultComp() walks past the expected func:function ancestor and treats an XML document node's ns pointer as element fields, causing an invalid memory read. Exploitation requires the stylesheet to be processed, and Red Hat reports a process crash only, with no data corruption or code execution.
