{"apiVersion":"1.0","identifier":"CVE-2026-74585","description":"In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Bound the DROM dual link port number before indexing sw->ports tb_drom_parse_entry_port() validates the device-supplied header->index against sw->config.max_port_number before indexing sw->ports[], but the sibling field entry->dual_link_port_nr -- a 6-bit value also read from the DROM -- indexes the same array with no such check. A malicious or malformed Thunderbolt device can set dual_link_port_nr beyond the allocated sw->ports[] (max_port_number + 1 entries), producing an out-of-bounds tb_port pointer that is stored and later dereferenced. Reject a port entry whose dual_link_port_nr exceeds max_port_number, the same bound already applied to header->index.","publishedAt":"2026-08-22T16:16:30","lastModifiedAt":"2026-08-22T16:16:30","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74585","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00177,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74585","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74585","en":"https://www.redsauce.net/en/cves/CVE-2026-74585","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74585","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74585","de":"https://www.redsauce.net/de/cves/CVE-2026-74585","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74585","el":"https://www.redsauce.net/el/cves/CVE-2026-74585"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74585"}}
