Описание
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().
Отчет
This bug leads to a memory leak if device registration fails, as a dynamically allocated name is not properly freed. Only a privileged user with the ability to register mISDN devices can trigger this condition. The impact is limited to minor memory loss in kernel space and does not affect confidentiality or integrity.
