Descriptions

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

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: hwmon: (axi-fan-control) Se corrigió la posible desreferencia del puntero NULL. Se podría llamar a axi_fan_control_irq_handler(), dependiente de la estructura privada axi_fan_control_data, antes de que se registre el dispositivo hwmon. Esto provocará el error "No se puede manejar la desreferencia del puntero NULL del kernel".
