The cpufreq\nnotifier remains registered even though initialization failed.\n\nMirror the module exit path on the init failure path and unregister the\ncpufreq notifier when it has been registered.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/06f32dd67e6b23a05bef0d8183c5335af91c0c3b","https://git.kernel.org/stable/c/182cd086b31ea4ccc1d8f2ec5b81e988dfe0b892","https://git.kernel.org/stable/c/64976f3b34b07eb866ead4052cefe7e9ff45fd2f","https://git.kernel.org/stable/c/8f3036c5de8b651880f323e223b1604b6cfbff21","https://git.kernel.org/stable/c/ccee0785030978c49505e04954eee3f30a5f01ca"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90364","score":0.00206,"percentile":0.1045,"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).
