Attack-Flow Graph

Executive Summary

This vulnerability is a race condition in the codecs component of Google Chrome on Windows versions prior to 149.0.7827.53. 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 means the attacker could gain higher privileges on the system, potentially leading to further compromise beyond the browser.
