If we\nalso have two netdevs (first one need only be a wdev though)\nthen we can find one during the first iteration, close it,\nand go to the second iteration -- but then find two, and try\nto destroy also the one we didn't close yet.\n\nFix this by only iterating once.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/241e633cb379c4f332fc1baf2abec95ec840cbeb","https://git.kernel.org/stable/c/c979f792a2baf6d0f3419587668a1a6eba46a3d2","https://git.kernel.org/stable/c/f0a6fd1527067da537e9c48390237488719948ed","https://git.kernel.org/stable/c/241e633cb379c4f332fc1baf2abec95ec840cbeb","https://git.kernel.org/stable/c/c979f792a2baf6d0f3419587668a1a6eba46a3d2"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2022-48784","score":0.00172,"percentile":0.0658,"date":"2026-10-31"},"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).
