It should not be\nnecessary to check console_is_registered() here since the function\nshould not be called in the fist place when the console is not\nregistered.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2f8e3cad53b5c36ab0ed5d3195bfc55c59ea61a5","https://git.kernel.org/stable/c/7d3f15a664d115584fc177b5f2cfbdb3e5a50d60","https://git.kernel.org/stable/c/be98f92fc244688a6bdecbc834cf2cd243056d9d","https://git.kernel.org/stable/c/d73441232f1f067eb659e94447b1353c16609711","https://git.kernel.org/stable/c/e5e11274b5512e24a346ed83f8dd85e3389d2f4b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90158","score":0.00209,"percentile":0.10911,"date":"2026-10-26"},"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).
