{"id":"AZL-96594","summary":"CVE-2026-72320 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nft_lookup: fix catchall element handling with inverted lookups\n\nnft_lookup_eval() decides whether a lookup matched (`found`) from the\ndirect set lookup and priv-\u003einvert before falling back to the\ncatchall element used by interval sets (e.g. nft_set_rbtree) for the\nopen-ended default range. 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().","modified":"2026-08-29T05:27:27Z","published":"2026-08-15T06:22:04Z","upstream":["CVE-2026-72320"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72320"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96594.json"}}],"schema_version":"1.9.0"}
