CVE-2026-41157 (GCVE-0-2026-41157)

Vulnerability from cvelistv5 – Published: 2026-06-12 21:53 – Updated: 2026-06-15 15:14

Title

GPU DDK - OOB Write in CalculateNPOTTwiddleSparsePageMap3D

Summary

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.

Severity

9.8 (Critical)

GHSA-2M3R-7R37-RW4C

Vulnerability from github – Published: 2026-06-13 00:34 – Updated: 2026-06-15 18:31

Details

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.

Severity

9.8 (Critical)
