If\nthe rhashtable insertion reports an error or an existing destination, the\nfunction discards its candidate but retains the reservation. No new path\nis installed in any of these cases.\n\nRelease the reservation whenever the candidate is not installed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/56691ed9ef792f180e008a43294a4dc059fbeca2","https://git.kernel.org/stable/c/57bfaa8b2853425ab1b83114d823a62fe63f859f","https://git.kernel.org/stable/c/7325a44474f20c1393a1c114c6811abce6ddfaf4","https://git.kernel.org/stable/c/a59eca4557c7462aad1b160011013290a92de97d","https://git.kernel.org/stable/c/a613c891906b558c10a4fa98ca29747b98e857cb"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98701","score":0.00168,"percentile":0.05985,"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).
