CVE-2022-49011 Information

Description

In the Linux kernel the following vulnerability has been resolved:

hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()

As comment of pci_get_domain_bus_and_slot() says it returns a pci device with refcount increment when finish using it the caller must decrement the reference count by calling pci_dev_put(). So call it after using to avoid refcount leak.
