Summary
Qt Framework from 6.5.0 before 6.8.10, from 6.9.0 before 6.11.3 and from 6.12.0 before 6.12.1 is affected. The assimp scene import plugin of the Qt3D module has an out-of-bounds write (CWE-787) that writes memory outside the intended bounds. A local user with no privileges can corrupt memory if a user interacts with the application, which affects integrity and availability.
