Executive Summary

This vulnerability involves improper input validation in the FullScreen feature of Google Chrome versions before 156.0.8078.47. A remote attacker could exploit this by tricking a user into visiting a specially crafted HTML page, potentially allowing arbitrary code execution within the browser's sandbox.
