Apps that register an asynchronous session.setPermissionRequestHandler() may be vulnerable to a use-after-free when handling fullscreen, pointer-lock, or keyboard-lock permission requests. If the requesting frame navigates or the window closes while the permission handler is pending, invoking the stored callback dereferences freed memory, which may lead to a crash or memory corruption.
Apps that do not set a permission request handler, or whose handler responds synchronously, are not affected.
Respond to permission requests synchronously, or deny fullscreen, pointer-lock, and keyboard-lock requests if an asynchronous flow is required.
