In the Linux kernel, the following vulnerability has been resolved: HID: elan: Fix potential double free in elan_input_configured 'input' is a managed resource allocated with devm_input_allocate_device(), so there is no need to call input_free_device() explicitly or there will be a double free. According to the doc of devm_input_allocate_device(): * Managed input devices do not need to be explicitly unregistered or * freed as it will be done automatically when owner device unbinds from * its driver (or binding fails).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: HID: elan: Se corrige una posible doble liberación en elan_input_configured 'input' es un recurso administrado asignado con devm_input_allocate_device(), por lo que no es necesario llamar a input_free_device() explícitamente o habrá una doble liberación. Según la documentación de devm_input_allocate_device(): * Los dispositivos de entrada administrados no necesitan ser desregistrados explícitamente o * liberados ya que se hará automáticamente cuando el dispositivo propietario se desvincule de * su controlador (o la vinculación falle).
