      "summary": "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->invert 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().",
