Technical details

A use-after-free (UAF) vulnerability exists in the User Interface (UI) component of Google Chrome. The flaw is triggered when the browser incorrectly manages memory for UI objects, allowing an attacker to reference memory after it has been freed. By leveraging a crafted HTML page, a remote, unauthenticated attacker can exploit this memory corruption to achieve a sandbox escape. This allows code execution outside of the restricted browser process at the privilege level of the user. The vulnerability is addressed in Chrome version 148.0.7778.168.
