Signalfd_poll() and binder_poll() use a waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed. We recommend upgrading past commit fc78b2fc21f10c4c9c4d5d659a685710ffa63659"},{"lang":"es","value":"Se presenta un uso de memoria previamente liberada en la función io_uring en el kernel de Linux. Signalfd_poll() y binder_poll() usan una cola de espera cuyo tiempo de vida es la tarea actual. Enviará una notificación POLLFREE a todos los esperadores antes de que la cola sea liberada. Desafortunadamente, el sondeo io_uring no maneja POLLFREE. Esto permite que sea producido un uso de memoria previamente liberada si un signalfd o binder fd es sondeado con io_uring poll, y la cola de espera es liberada.
