"value": "AV:L - The bug is triggered via the nfnetlink/nf_tables control plane (NFT_MSG_NEWSET with timeout attributes on an anonymous set, then rule delete), which requires a local netlink socket; nftables netlink is a Local attack vector.\nAC:L - The attacker fully controls both sides of the race by setting NFTA_SET_TIMEOUT/NFTA_SET_GC_INTERVAL (driving async rhash/pipapo GC frequency and element expiry) and issuing the unbind/delete transaction, and can retry indefinitely until the GC batch races with set teardown.\nPR:L - nfnetlink_rcv() only requires CAP_NET_ADMIN in the network namespace’s user_ns via netlink_net_capable(), which an unprivileged user obtains with unshare -Urn; nftables is fully functional per-netns.\nUI:N - Creating the anonymous timeout set, populating expiring elements, and deleting the binding rule are all performed by the attacker’s own process with no victim action.\nS:U - The resulting use-after-free corrupts kernel heap state within the same kernel security authority; this is standard local privilege escalation with no VM/IOMMU/sandbox boundary crossed.\nC:H - The GC-vs-destroy race yields a use-after-free on nft_rhash_elem/set objects whose size and contents the attacker chooses, enabling heap spray and arbitrary kernel memory disclosure; per guidance any UAF is Confidentiality High.\nI:H - Concurrent GC removal and set destroy produce UAF/double-free of attacker-sized slab objects—the same nftables heap-corruption primitive class used for local privilege escalation (as in related CVE-2024-26642/26643)—so Integrity is High.\nA:H - Even without successful exploitation, the UAF/double-free on set elements and the destroyed rhashtable causes slab corruption and kernel oops/panic, and the attacker can trigger it repeatedly."
