When RDMA device registration fails, the registration\nworker's err_dealloc_ctx path calls c4iw_dealloc() directly, bypassing\nc4iw_remove(), so the debugfs dentries leak and outlive the freed\nc4iw_dev.\n\nMove debugfs_remove_recursive() into c4iw_dealloc() so every path that\nfrees ctx->dev also removes its debugfs tree.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/046425412529dbfca1433c8bef5641b271b4ab2a","https://git.kernel.org/stable/c/459b59f7ed56511d6529311cb4e5e482ebfcfb8e","https://git.kernel.org/stable/c/479a7f90060e62bdd9bb4036ec0a70bf460f6d23","https://git.kernel.org/stable/c/c332d9e7dce234d8bef78271d003a68ee943b61b","https://git.kernel.org/stable/c/cd60992f09b7e83bfd3c76e3bb06b29f3e2fa0a8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90219","score":0.00227,"percentile":0.1332,"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).
