CVE-2023-53304 is a resource-management flaw in the Linux kernel netfilter nft_set_rbtree implementation. During lazy garbage collection performed when inserting timed-out nftables interval-set entries, the overlap-expiration walk can fail to release the other half of an interval. The affected logic also incorrectly handles reverse-tree traversal results and does not properly validate whether an end interval is active in the current generation.
