  "details": "In the Linux kernel, the following vulnerability has been resolved:  of/address: Fix NULL bus dereference in of_pci_range_parser_one()  The bus matching rework made of_match_bus() return NULL for nodes with ranges/dma-ranges but no local #address-cells. parser_init() stored that NULL bus, and the range iterator later dereferenced it.  Reject such nodes in parser_init(), leaving an explicit empty iterator for callers that ignore the init return, and make of_dma_get_max_cpu_address() honour the init failure so a rejected node cannot clamp the DMA limit.",
