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.

kernel: hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()
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.
A counting logic flaw exists in the Linux kernel. When ci_get_domain_bus_and_slot() is called, it returns a pci device with refcount incremented. When finishing it,
the caller must decrement the reference count by calling pci_dev_put(), leading to the loss of confidentiality of the system.
Statement: This issue is fixed in RHEL-9.4 and above:
