{"apiVersion":"1.0","identifier":"CVE-2026-74679","description":"In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_ncm: Use unsigned int for ndp_index The variable ndp_index is declared as a signed integer, but it stores the return value of get_ncm(), which is unsigned. A malicious host can supply a large offset that overflows the signed ndp_index, making it negative. Because ndp_index is compared against unsigned bounds, this negative value bypasses sanity checks and leads to an out-of-bounds read when calculating the address of the NDP block (ntb_ptr + ndp_index). Fix this by changing ndp_index to unsigned int to ensure consistent unsigned comparisons throughout the function.","publishedAt":"2026-08-22T16:16:42","lastModifiedAt":"2026-08-22T16:16:42","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74679","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00185,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74679","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74679","en":"https://www.redsauce.net/en/cves/CVE-2026-74679","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74679","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74679","de":"https://www.redsauce.net/de/cves/CVE-2026-74679","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74679","el":"https://www.redsauce.net/el/cves/CVE-2026-74679"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74679"}}
