In the Linux kernel, the following vulnerability has been resolved: mISDN: fix possible memory leak in mISDN_register_device() Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, add put_device() to give up the reference, so that the name can be freed in kobject_cleanup() when the refcount is 0. Set device class before put_device() to avoid null release() function WARN message in device_release().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mISDN: se corrige una posible pérdida de memoria en mISDN_register_device() Después de el commit 1fa5ae857bb1 ("núcleo del controlador: deshacerse de la matriz de cadenas bus_id del dispositivo de estructura"), el nombre del dispositivo se asigna dinámicamente, agregue put_device() para renunciar a la referencia, de modo que el nombre se pueda liberar en kobject_cleanup() cuando el refcount sea 0. Establezca la clase del dispositivo antes de put_device() para evitar el mensaje WARN de la función release() nula en device_release().
