What is CVE-2025-10729?

The Qt SVG module contains a vulnerability where a node can be created outside of a structural node. Although this node is deleted instantly after its creation, it may still be accessed later in the program flow, leading to a use after free scenario. This can potentially allow attackers to exploit the situation to execute arbitrary code or cause application crashes.
