{"apiVersion":"1.0","identifier":"CVE-2026-72320","description":"In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_lookup: fix catchall element handling with inverted lookups nft_lookup_eval() decides whether a lookup matched (`found`) from the direct set lookup and priv->invert before falling back to the catchall element used by interval sets (e.g. nft_set_rbtree) for the open-ended default range. Since `found` is never recomputed after `ext` is replaced by the catchall lookup, inverted lookups (NFT_LOOKUP_F_INV, -!= @set-) can wrongly match or wrongly skip the catchall element, producing the wrong verdict. Fold the catchall lookup into `ext` before computing `found`, matching the order already used by nft_objref_map_eval().","publishedAt":"2026-08-15T06:22:04","lastModifiedAt":"2026-08-17T06:18:35","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72320","cvssScore":9.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","epssProbability":0.00523,"riskScore":0.95,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72320","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72320","en":"https://www.redsauce.net/en/cves/CVE-2026-72320","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72320","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72320","de":"https://www.redsauce.net/de/cves/CVE-2026-72320","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72320","el":"https://www.redsauce.net/el/cves/CVE-2026-72320"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72320"}}
