CVE-2022-48896 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ixgbe: fix pci device refcount leak

As the comment of pci_get_domain_bus_and_slot() says it returns a PCI device with refcount incremented when finish using it the caller must decrement the reference count by calling pci_dev_put().

In ixgbe_get_first_secondary_devfn() and ixgbe_x550em_a_has_mii() pci_dev_put() is called to avoid leak.
