Therefore, the allocate\nnode instances can be safely released by traversing the linked list from\nits head.\n\nRelease the remaining node instances with for_each_fw_node() before\nreturning to the caller.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/05bfb1327dc5fb61528bab31cd8f0c1e4bddec23","https://git.kernel.org/stable/c/45c534c5bf43a094805a79510d1ea3ca261ea042","https://git.kernel.org/stable/c/6a990e74d4e848f32eda91d69e4f885604fc326d","https://git.kernel.org/stable/c/848eaef4d30b385eb074214b7fa58287506158ad","https://git.kernel.org/stable/c/d6037e42aa4dd29bb9d9f67ef438128c5bfe3448"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-90213","score":0.00207,"percentile":0.10735,"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).
