A vulnerability in the Linux kernel's PCI device tree handling was resolved. The issue occurs when a PCI bridge device lacks a subordinate bus, causing certain dynamic device tree helper functions to dereference a null pointer. This can lead to a NULL pointer dereference and an early boot hang when the PCI dynamic device tree nodes feature is enabled. The fix ensures that 'bus-range' and 'interrupt-map' properties are only generated if a subordinate bus exists, preventing the null dereference. The vulnerability was introduced in kernel version 6.15 and affects configurations with CONFIG_PCI_DYNAMIC_OF_NODES enabled.
