Last modified
CVE-2022-48896 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
