GPU-process heap corruption via shader double-free
Published Apr 10, 2024 · Updated Feb 13, 2025
Use-after-free in Dawn in Google Chrome before 123.0.6312.122 allows remote attackers to corrupt GPU-process heap memory via crafted HTML. A WebGPU shader containing a self-assignment of a static struct causes the shader pipeline to free the same object twice during optimization. The target must visit attacker-controlled HTML, which automatically processes the shader and can crash the GPU process.
