CVE-2026-11573: CWE-674: Uncontrolled Recursion in qt
Uncontrolled recursion in Qt's QDomDocument serialization (QtXml) lets deeply nested untrusted XML crash the app via stack exhaustion (DoS only).
AI Analysis
Technical Summary
This vulnerability arises from uncontrolled recursion in Qt's QDomDocument serialization (QtXml) implementation. When processing deeply nested XML documents, the recursion depth can exhaust the stack, causing the application to crash. The issue affects Qt version 6.7.0. No official remediation or patch is currently documented, and no known exploits are reported in the wild.
Potential Impact
An attacker can supply crafted deeply nested XML input to cause the application using Qt 6.7.0 to crash due to stack exhaustion. This results in a denial of service condition, impacting application availability but not confidentiality or integrity.
Mitigation Recommendations
No official fix or patch has been published yet. Users should monitor the vendor advisory for updates. Until a patch is available, avoid processing untrusted or deeply nested XML documents with Qt 6.7.0 to reduce risk.
