Attack-Flow Graph

Executive Summary

This vulnerability is an out of bounds read in the Skia graphics library used by Google Chrome on Mac systems prior to version 150.0.7871.47.

It allows a remote attacker who has already compromised the renderer process to leak cross-origin data by using a specially crafted HTML page.

Impact Analysis

If exploited, this vulnerability can lead to unauthorized disclosure of sensitive information from other origins (websites) due to cross-origin data leakage.

This means an attacker controlling the renderer process could access data they should not have permission to see, potentially compromising user privacy and security.

Compliance Impact

This vulnerability allows a remote attacker who has compromised the renderer process to leak cross-origin data via a crafted HTML page. Such unauthorized data leakage could potentially lead to exposure of sensitive personal or protected health information.

As a result, organizations using affected versions of Google Chrome on Mac may face increased risk of non-compliance with data protection regulations such as GDPR and HIPAA, which require safeguarding personal and health information against unauthorized access and disclosure.
