Executive brief
Google Chrome is a widely used web browser. A vulnerability in its media handling component could allow an attacker to execute malicious code on a user's computer if they visit a specially crafted website. While the attack is limited by the browser's security sandbox, it could still lead to unauthorized data access or be used as part of a larger attack to compromise the entire system.
Technical details
A use-after-free (UAF) vulnerability exists in the Media component of Google Chrome. The flaw is triggered when the browser incorrectly manages memory during the processing of media content, allowing an attacker to reference memory after it has been freed. By enticing a user to visit a malicious website, a remote attacker can exploit this condition to achieve arbitrary code execution within the context of the Chromium sandbox. The vulnerability was addressed in version 148.0.7778.168 for Windows, Mac, and Linux.
