Sources and claim methodology

  • Source referenceimaginationtech.com
Upstream source description

A web page that contains unusual WebGPU content loaded into the GPU GLES render process can trigger a OOB read and/or write crash in the GPU GLES user-space shared library. On certain platforms, when the process executing graphics workload has system privileges this could enable further exploits on the device.
