In the Linux kernel, the following vulnerability has been resolved:
hwmon: (coretemp) fix pci device refcount leak in nv1aramnew()
As comment of pcigetdomainbusandslot() says, it returns a pci device with refcount increment, when finish using it, the caller must decrement the reference count by calling pcidev_put(). So call it after using to avoid refcount leak.
