Attack-Flow Graph

Executive Summary

This vulnerability involves insufficient validation of untrusted input in the Dawn component of Google Chrome on Linux and ChromeOS versions prior to 149.0.7827.103. A remote attacker who has already compromised the renderer process could exploit this flaw by using a specially crafted HTML page to potentially escape the browser's sandbox environment.

Impact Analysis

If exploited, this vulnerability could allow an attacker to escape the sandbox that normally restricts the renderer process. This means the attacker could gain higher privileges on the affected system, potentially leading to unauthorized access to system resources, data theft, or further compromise of the device.
