Vulnerability Title
GPU DDK - OOB Write in CalculateNPOTTwiddleSparsePageMap3D
Source: NVD (National Vulnerability Database)
Vulnerability Description
A web page that contains unusual WebGPU content loaded into the GPU GLES render process and can trigger an out-of-bound write in the GPU user-space driver, leading to memory corruption and possible browser/GPU process crash. The software computes a required memory size from untrusted input, but integer overflow can produce a value smaller than needed. Subsequent write operations may then occur past the intended memory boundary, corrupting adjacent memory and causing process instability or termination.
