The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still present in\nthe current wireless tree.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\ncompatible Libertas USB hardware for exercising this firmware-download\npath, no runtime testing was able to be performed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/63c2391deefb31e1b801b7f32bd502ca4808639b","https://git.kernel.org/stable/c/644640cde2fb216e6567de5eee780a38dbc95928","https://git.kernel.org/stable/c/6c1f54a04813676c5a2150d99331c8d21f199374","https://git.kernel.org/stable/c/6cda91bbb8dc3d22ef0323008a12dcf73a5129da","https://git.kernel.org/stable/c/7f28722b3e4e0c8d49c859fea4a9b1fa13b5ae06"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68410","score":0.00216,"percentile":0.12131,"date":"2026-11-01"},"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).
