{"apiVersion":"1.0","identifier":"CVE-2026-74491","description":"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.","publishedAt":"2026-08-15T13:17:54","lastModifiedAt":"2026-08-17T06:19:45","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74491","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00166,"riskScore":0,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74491","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74491","en":"https://www.redsauce.net/en/cves/CVE-2026-74491","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74491","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74491","de":"https://www.redsauce.net/de/cves/CVE-2026-74491","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74491","el":"https://www.redsauce.net/el/cves/CVE-2026-74491"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74491"}}
