Since `found` is never recomputed after\n`ext` is replaced by the catchall lookup, inverted lookups\n(NFT_LOOKUP_F_INV, \"!= @set\") can wrongly match or wrongly skip the\ncatchall element, producing the wrong verdict. Fold the catchall\nlookup into `ext` before computing `found`, matching the order\nalready used by nft_objref_map_eval().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1},"cwes":[],"references":["https://git.kernel.org/stable/c/0ab8880865f9678eb6174e72c1fc4712e44c745c","https://git.kernel.org/stable/c/238c612357b5a25f03eacf356f95034f8551f218","https://git.kernel.org/stable/c/65d35cb555f40529a9edc6bf4beaa3bee917f015","https://git.kernel.org/stable/c/e6107a4c74b54cb33e3bce162a63048ae5a6b198","https://git.kernel.org/stable/c/ef0c7d4b04a0e6ad175323c24bc84e11470dd79d"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-72320","score":0.00523,"percentile":0.44082,"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).
