"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: gpiolib: reparar p\u00e9rdida de memoria en gpiochip_setup_dev() Aqu\u00ed hay un informe de seguimiento sobre la p\u00e9rdida de memoria detectada en gpiochip_setup_dev(): objeto sin referencia 0xffff88810b406400 (tama\u00f1o 512): comm \"python3\", pid 1682, jiffies 4295346908 (edad 24.090s) seguimiento: kmalloc_trace device_add device_private_init en drivers/base/core.c:3361 (en l\u00ednea por) device_add en drivers/base/core.c:3411 cdev_device_add gpiolib_cdev_register gpiochip_setup_dev gpiochip_add_data_with_key gcdev_register() y gcdev_unregister() llamar\u00edan device_add() y device_del() (sin importar si CONFIG_GPIO_CDEV est\u00e1 habilitado o no) para registrar/anular el registro del dispositivo. Sin embargo, si device_add() tiene \u00e9xito, alg\u00fan recurso (como la estructura device_private asignada por device_private_init()) no es liberado por device_del(). Por lo tanto, despu\u00e9s de que device_add() tenga \u00e9xito por gcdev_register(), necesita llamar a put_device() para liberar el recurso en la ruta del controlador de error. Aqu\u00ed avanzamos el registro de la funci\u00f3n de liberaci\u00f3n y dejamos que libere cada pieza de recurso por put_device() en lugar de kfree(). Mientras lo hacemos, solucionamos otro problema sutil, es decir, cuando gc->ngpio es igual a 0, todav\u00eda llamamos a kcalloc() y, en caso de un error adicional, a kfree() en el puntero ZERO_PTR, que no es NULL. No es un error en s\u00ed, sino m\u00e1s bien un desperdicio de recursos y una expectativa potencialmente err\u00f3nea sobre el contenido de la variable gdev->descs."
