Out-of-Bounds Write Vulnerability in GPU Shader Compiler from Imagination Technologies

CVE-2026-21734

What is CVE-2026-21734?

This vulnerability in the GPU shader compiler library allows for an out-of-bounds write crash triggered by unusual GPU shader code. When loaded into the GPU compiler process, specific edge cases involving very small values can cause a segmentation fault. On certain platforms where the compiler operates with elevated system privileges, this poses a risk for further exploits, potentially compromising the device's integrity.
