CVE-2026-79240Network attack vector

Sandboxed code execution via HLSL name collision

Published Aug 25, 2026 · Updated Aug 25, 2026

Out-of-bounds write in ANGLE in Google Chrome for Windows before 152.0.7977.65 allows remote attackers to execute code inside the sandbox. ANGLE's HLSL translator failed to distinguish colliding function-parameter and local-variable names, producing incorrect shader output that writes beyond a buffer boundary. Exploitation requires a user to load crafted HTML, and the resulting code execution remains confined to Chrome's sandbox absent a separate escape.
