  "details": "In the Linux kernel, the following vulnerability has been resolved:  PCI: of_property: Omit bus properties without a subordinate bus  A bridge (a device with a Type 1 header) may not have a secondary bus allocated (pdev-\u003esubordinate), e.g., if there are no available bus numbers or the bridge secondary/subordinate bus numbers are not writable.  The dynamic OF helpers of_pci_prop_bus_range() and of_pci_prop_intr_map() dereference pdev-\u003esubordinate without checking it.  When CONFIG_PCI_DYNAMIC_OF_NODES is enabled, this can cause a NULL pointer dereference and early boot hang.  Generate 'bus-range' and 'interrupt-map' properties only when a subordinate bus exists.  Keep the node and its remaining properties for bridges without one.  The problem was latent since 407d1a51921e (\"PCI: Create device tree node for bridge\"), but wasn't reachable until 1f340724419e (\"PCI: of: Create device tree PCI host bridge node\"), which appeared in v6.15.  Before 1f340724419e, of_pci_make_dev_node() returned early because the parent OF node was missing.  [bhelgaas: move pdev-\u003esubordinate test to callees, commit log]",
