Executive Summary

This vulnerability involves insufficient validation of untrusted input in the Codecs component of Google Chrome versions prior to 149.0.7827.53. A remote attacker could exploit this by using a specially crafted video file to potentially escape the browser's sandbox environment.

Impact Analysis
