## Technical details

A use-after-free (UAF) vulnerability exists in the 'Core' component of Google Chrome for iOS. The flaw is triggered when the browser incorrectly manages memory during the processing of specially crafted HTML content. An attacker who has already achieved code execution within the sandboxed renderer process can leverage this UAF to escape the sandbox and execute arbitrary code with higher privileges on the iOS system. The vulnerability is addressed in version 149.0.7827.53.
