The same data is\nthen used later in the function, hence the UAF.\n\nFix by moving the accesses to btusb data to before the data is free'd.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/1c28c1e1522c773a94e26950ffb145e88cd9834b","https://git.kernel.org/stable/c/23d22f2f71768034d6ef86168213843fc49bf550","https://git.kernel.org/stable/c/297dbf87989e09af98f81f2bcb938041785557e8","https://git.kernel.org/stable/c/5dc00065a0496c36694afe11e52a5bc64524a9b8","https://git.kernel.org/stable/c/7a6d1e740220ff9dfcb6a8c994d6ba49e76db198"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-40283","score":0.00142,"percentile":0.03476,"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).
