Thus, make a copy in\nusb_probe_interface. Clarify the documentation that the id parameter is\nonly valid during the probe.\n\nUSB serial has the same pattern, but it does not need fixing as the IDs\ncannot be removed via sysfs.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/44904468e58d3dc3a0229782acbeb9677b060541","https://git.kernel.org/stable/c/64320c6e721bdec4c43a789c866c8a099dd0c843","https://git.kernel.org/stable/c/7e795801295c84a6bbc10a3e7a4c99c50bfe45ac","https://git.kernel.org/stable/c/9b82ddf76827e2a8ff033a8131ecf24f2d6cae26","https://git.kernel.org/stable/c/e6a9c6b79b70046afdf5a1dbd03b1104536f30c0"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93117","score":0.00205,"percentile":0.10439,"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).
