Technical details
An improper input validation vulnerability (CWE-20) exists in the Dawn component of Google Chrome for Linux and ChromeOS. Dawn is the implementation of the WebGPU standard in Chromium. The vulnerability is reachable by a remote attacker who can entice a user to visit a specially crafted HTML page. A successful exploit requires the attacker to have already achieved code execution within the sandboxed renderer process; from there, the insufficient validation in Dawn allows for a sandbox escape to the browser process or host operating system. Google has addressed this in version 149.0.7827.103.
