Both are taken independently from different endpoints\nin usbio_probe(), so the check is wrong when they differ.\n\nUse rxbuf_len for the IN direction.  This matches the buffer that\nactually holds the response data.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/7e22c9f79b200672f3e477421b6c9050d8cf70a5","https://git.kernel.org/stable/c/9ad0164f78b66b0b5eca3a5748cc94dd87e28124","https://git.kernel.org/stable/c/ebfd1e82ab0a6d26efd9bdd89de899215851f5bf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-74681","score":0.00206,"percentile":0.10592,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
