3Description
A web page that contains unusual GPU shader code is loaded into the GPU compiler process and can trigger a write out-of-bounds write crash in the GPU shader compiler library. On certain platforms, when the compiler process has system privileges this could enable further exploits on the device. An edge case using a very large value in switch statements in GPU shader code can cause a segmentation fault in the GPU shader compiler due to an out-of-bounds write access.
Analysis
GPU shader compiler memory corruption via malicious shader code allows remote code execution when the compiler runs with elevated privileges, affecting multiple platforms through crafted switch statements that trigger out-of-bounds writes. An attacker can exploit this vulnerability by delivering specially-crafted GPU shader code through a web page, potentially gaining system-level control on vulnerable devices. …
