  3. CVE-2023-52652
In the Linux kernel, the following vulnerability has been resolved: NTB: fix possible name leak in ntb_register_device() If device_register() fails in ntb_register_device(), the device name allocated by dev_set_name() should be freed. As per the comment in device_register(), callers should use put_device() to give up the reference in the error path. So fix this by calling put_device() in the error path so that the name can be freed in kobject_cleanup(). As a result of this, put_device() in the error path of ntb_register_device() is removed and the actual error is returned. [mani: reworded commit message]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: NTB: corrige una posible fuga de nombre en ntb_register_device() Si device_register() falla en ntb_register_device(), se debe liberar el nombre del dispositivo asignado por dev_set_name(). Según el comentario en device_register(), las personas que llaman deben usar put_device() para abandonar la referencia en la ruta de error. Así que solucione este problema llamando a put_device() en la ruta del error para que el nombre pueda liberarse en kobject_cleanup(). Como resultado de esto, put_device() en la ruta de error de ntb_register_device() se elimina y se devuelve el error real. [mani: mensaje de confirmación reformulado]
