CVE-2025-10729: CWE-416 Use After Free in Qt
The module will parse a <pattern> node which is not a child of a structural node. The node will be deleted after creation but might be accessed later leading to a use after free.
AI Analysis
Technical Summary
This vulnerability in Qt involves improper handling of a <pattern> node during XML parsing. The node is deleted after creation but may be accessed afterward, resulting in a use-after-free condition (CWE-416). The CVSS 4.0 base score is 9.4, indicating critical severity with high impact on confidentiality, integrity, and availability. The vulnerability affects Qt versions 6.7.0 and 6.9.0. No patch or official fix information is provided in the available data.
Potential Impact
Successful exploitation of this use-after-free vulnerability can lead to memory corruption, which may allow an attacker to execute arbitrary code, crash the application, or cause denial of service. The CVSS vector indicates local attack vector with low complexity, no privileges or user interaction required, and high impact on all security properties.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor Qt vendor communications for updates. Until a fix is available, avoid processing untrusted XML data that could trigger this vulnerability.
