A flaw was found in Google Chrome. A remote attacker could exploit a use-after-free vulnerability in the PrivateAI component by convincing a user to engage in specific user interface (UI) gestures through a crafted HTML page. This could potentially allow the attacker to bypass the browser's security sandbox, leading to unauthorized access or control over the system.
