CVE-2024-25580

Application crash via unbounded KTX memory reads

Published Mar 27, 2024 · Updated Nov 4, 2025

Buffer overflow in Qt QKtxHandler allows local users to crash affected applications by supplying a crafted KTX image file. The parser in gui/util/qktxhandler.cpp fails to bound memory reads against attacker-controlled KTX contents, producing an out-of-bounds read and buffer overflow. Reachability requires a local application to process the file; published impact is limited to an application crash, with no disclosed data exposure or code execution.
