If the chip write\noperation returns an error other than -EOPNOTSUPP, the code jumps to the\nput label, which calls put_device(hdev). If this drops the final reference,\nthe device is freed. When the function then returns, the guard cleanup\nfunction runs and attempts to unlock the freed mutex.\n\nUse scoped_guard() instead of guard() to avoid the problem.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/01dd8b4fc2cf83c66565c0f382fb1841e9000a89","https://git.kernel.org/stable/c/354ccc99b2dc8ba0cf6d4de34e520bcf6ecca5c2","https://git.kernel.org/stable/c/8afab57bcdbc2186f325972e777880ac5a220f4f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-98000","score":0.00166,"percentile":0.05774,"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).
