CVE-2026-74491 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionIn 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.
