{"apiVersion":"1.0","identifier":"CVE-2026-74681","description":"In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: check ibuf_len against rxbuf_len in bulk msg ibuf_len is the bulk IN (receive) buffer size, but the EMSGSIZE check in usbio_bulk_msg() compares it against txbuf_len — the bulk OUT endpoint size. Both are taken independently from different endpoints in usbio_probe(), so the check is wrong when they differ. Use rxbuf_len for the IN direction. This matches the buffer that actually holds the response data.","publishedAt":"2026-08-22T16:16:42","lastModifiedAt":"2026-08-22T16:16:42","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74681","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-2026-74681","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74681","en":"https://www.redsauce.net/en/cves/CVE-2026-74681","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74681","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74681","de":"https://www.redsauce.net/de/cves/CVE-2026-74681","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74681","el":"https://www.redsauce.net/el/cves/CVE-2026-74681"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74681"}}
