Executive Summary

This vulnerability is a race condition in the Safe Browsing feature of Google Chrome on Mac systems prior to version 149.0.7827.155. 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 can allow an attacker to escape the sandbox environment of the browser, which is designed to isolate processes and limit their access to the system. This could lead to the attacker gaining higher privileges on the affected system, potentially allowing them to execute arbitrary code, access sensitive information, or cause significant harm.
