CVE-2025-9714 – Stack overflow in libxml2

CVE ID : CVE-2025-9714

Published : Sept. 10, 2025, 7:15 p.m. | 1 hour, 24 minutes ago

Description : Uncontrolled recursion in XPath evaluation in libxml2 up to and including version 2.9.14 allows a local attacker to cause a stack overflow via crafted expressions. XPath processing functions `xmlXPathRunEval`, `xmlXPathCtxtCompile`, and `xmlXPathEvalExpr` were resetting recursion depth to zero before making potentially recursive calls. When such functions were called recursively this could allow for uncontrolled recursion and lead to a stack overflow. These functions now preserve recursion depth across recursive calls, allowing recursion depth to be controlled.

Severity: 6.2 | MEDIUM
