Executive Summary

This vulnerability is a heap buffer overflow in the Codecs component of Google Chrome on Linux and ChromeOS versions prior to 149.0.7827.115.

It allows a remote attacker who has already compromised the renderer process to potentially escape the browser's sandbox by using a specially crafted HTML page.

Impact Analysis

If exploited, this vulnerability could allow an attacker to break out of the sandbox environment that normally restricts the renderer process.

This could lead to the attacker gaining higher privileges on the affected system, potentially allowing them to execute arbitrary code or access sensitive information.
