Attack-Flow Graph

Executive Summary

This is a race condition vulnerability in the FileSystem component of Google Chrome before version 152.0.7977.65. A race condition occurs when the behavior of a system depends on the sequence or timing of uncontrollable events. In this case, it allows an attacker who has already compromised the renderer process to potentially execute arbitrary code outside the Chrome sandbox by tricking a user into visiting a specially crafted HTML page.

Impact Analysis

If you are using an affected version of Google Chrome, this vulnerability could allow an attacker to run malicious code on your computer even if you are browsing in a sandboxed environment. This could lead to unauthorized access to your system, data theft, or installation of additional malware. Users should update Chrome to the latest version to mitigate this risk.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the race condition in the FileSystem component.
