AnalysisAI
In Qt 6.5.4, 6.5.5, and 6.6.2, QNetworkReply header data might be accessed via a dangling pointer in Qt for WebAssembly (wasm). Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Use After Free vulnerability could allow attackers to access freed memory to execute arbitrary code or crash the application.
Technical ContextAI
This vulnerability is classified as Use After Free (CWE-416), which allows attackers to access freed memory to execute arbitrary code or crash the application. In Qt 6.5.4, 6.5.5, and 6.6.2, QNetworkReply header data might be accessed via a dangling pointer in Qt for WebAssembly (wasm). (Earlier and later versions are unaffected.) Affected products include: Qt.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Use smart pointers or garbage-collected languages. Set pointers to NULL after freeing. Enable memory sanitizers.
