In the Linux kernel, the following vulnerability has been resolved:
hwmon: (axi-fan-control) Fix possible NULL pointer dereference
axifancontrolirqhandler(), dependent on the private axifancontrol_data structure, might be called before the hwmon device is registered. That will cause an "Unable to handle kernel NULL pointer dereference" error.
