Technical details
A use-after-free (UAF) vulnerability exists in the GPU GLES user-space shared library of the Imagination Technologies GPU DDK. The flaw is triggered when the GPU GLES render process processes 'unusual' WebGPU content from a web page. An attacker can exploit this memory corruption to cause a write-after-free condition. On platforms where the graphics workload process operates with elevated system privileges, this can be leveraged to achieve further exploitation or arbitrary code execution. The vulnerability affects DDK versions up to and including 25.2 RTM and is addressed in version 25.3 RTM.
