If platform_driver_register() fails, the function\nreturns the error directly and leaves the connector callback registered.\n\nThe later platform-device failure path already unregisters the callback.\nAdd the same cleanup before the final return when platform-driver\nregistration fails.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.","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/0352fdac3cbf11e3b323322ff8cd95e20cbf5cd7","https://git.kernel.org/stable/c/17518e7123f7ef01b1155064dc01f2087583908e","https://git.kernel.org/stable/c/466a8af0dee2cf745307155e26884e19a37b7e15","https://git.kernel.org/stable/c/9e768ae51426af2034d479133cfd73010d641b1a","https://git.kernel.org/stable/c/9eb7b3cbe99c9c0edbff69eb155c723e30983c22"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89597","score":0.00169,"percentile":0.06196,"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).
