  "details": "A type confusion vulnerability in Qt SVG allows an attacker to cause an application crash via a crafted SVG image.    When processing SVG marker references, the renderer retrieves a node by its id attribute and casts it to QSvgMarker* without verifying the node type. A non-marker element (such as a \u003cline\u003e element) that references itself as a marker triggers an out-of-bounds heap read due to the object size difference between QSvgLine and QSvgMarker,  followed by an endless recursion that bypasses the marker recursion  guard through incorrect virtual dispatch. The result is an application  crash (denial of service).    This issue affects Qt SVG:  from 6.7.0 before 6.8.8, from 6.9.0 before 6.11.1.",
