What it is

In the Linux kernel, the following vulnerability has been resolved:

PCI: Fix UAF when probe runs concurrent to dyn ID removal

Dynamic IDs are only guaranteed to be valid when dynids.lock is held,

as remove_id_store() can free the node. Thus, make a copy in

pci_match_device(). Also, clarify that the id parameter is only valid

during probe.
