Technical details

An uninitialized use vulnerability (CWE-457) exists in the Dawn component of Google Chrome on ChromeOS. Dawn is the underlying implementation of the WebGPU standard. The flaw allows a remote attacker to bypass memory safety protections by serving a specially crafted HTML page that triggers the use of uninitialized variables within the Dawn process. Successful exploitation enables the attacker to read potentially sensitive information from the browser's process memory. The issue is addressed in ChromeOS version 150.0.7871.46.
