Sandbox escape use-after-free in Chrome Dawn WebGPU
CVE-2026-6310 is a high-severity use-after-free vulnerability in Dawn, Chromium’s WebGPU implementation, affecting Google Chrome prior to 147.0.7727.101. The flaw is caused by improper lifetime management of GPU-related resources in Dawn, where freed objects can remain reachable through stale references, creating a dangling pointer condition. According to the provided content, an attacker who has already compromised the renderer process can trigger the bug via a crafted HTML page that issues crafted WebGPU commands, potentially causing memory corruption and hijacking execution flow across the renderer-to-GPU-process security boundary. Google tracked the issue under restricted Chromium issue 497969820 and patched it in Chrome 147.0.7727.101/.102 depending on platform.
