Heap buffer overflow in WebGL in Google Chrome prior to 146.0.7680.165 allowed a remote attacker to perform an out-of-bounds memory read via a crafted HTML page. The vulnerability resides in Chrome's WebGL graphics rendering component and was reported by the same pseudonymous researcher (_86ac1f1587b71893ed2ad792cd7dde32_) who discovered CVE-2026-5281 (Dawn WebGPU use-after-free zero-day under active exploitation) and CVE-2026-4676 (Dawn use-after-free with sandbox escape potential). This cluster of GPU-layer vulnerabilities suggests systematic fuzzing or targeted research into Chrome's graphics subsystem. The flaw was patched on March 23, 2026 as part of a Chrome Stable Channel update. All Chromium-based browsers including Microsoft Edge, Brave, Opera, and Vivaldi were affected until they incorporated the upstream fix.
