If driver_register() fails, those requests remain in the global\nIDR and retain pointers to the module's ID table. Once the failed module\nload releases that storage, later request matching or SCMI device creation\ncan dereference the stale pointers.\n\nUnrequest the complete protocol table before returning the registration\nfailure. At this point table registration succeeded, so every entry is\nowned by the current registration attempt.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/06e65e07a1bcb39a1ebc8bb89a981f8e07900497","https://git.kernel.org/stable/c/4520d4a1db37198756ad23568e36cdf091b6ffff","https://git.kernel.org/stable/c/524e57035af2d32498af9dd8fa6fdc92fcc8f80a","https://git.kernel.org/stable/c/9f7cd6a62aa754ed6b48cbd5d50de40add1bcc86","https://git.kernel.org/stable/c/a76b20b1f03099204db29b90e1024fe1c2b2cdd7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-92490","score":0.00209,"percentile":0.10919,"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).
