In the Linux kernel, the following vulnerability has been resolved:
net: libwx: fix VF illegal register access
Register WX_CFG_PORT_ST is a PF restricted register. When a VF is
initialized, attempting to read this register triggers an illegal
register access, which lead to a system hang.
When the device is VF, the bus function ID can be obtained directly from
the PCI_FUNC(pdev->devfn).
