CVE-2026-74491
|
| Sažetak |
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. |
