In the Linux kernel, the following vulnerability has been resolved:
ax25: Fix netdev refcount issue
The dev_tracker is added to ax25_cb in ax25_bind(). When the ax25 device is detaching, the dev_tracker of ax25_cb should be deallocated in ax25_kill_by_device() instead of the dev_tracker of ax25_dev. The log reported by ref_tracker is shown below:

Change ax25_dev->dev_tracker to the dev_tracker of ax25_cb in order to mitigate the bug.
