Title
netfilter: nf_tables: disallow anonymous set with timeout flag
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: disallow anonymous set with timeout flag
Anonymous sets are never used with timeout from userspace, reject this.
Exception to this rule is NFT_SET_EVAL to ensure legacy meters still work.
Severity

"value": "AV:L - The vulnerable configuration is created and destroyed through the nfnetlink/nf_tables netlink interface (NFT_MSG_NEWSET/NEWSETELEM/DELRULE), which requires a local socket on the system. Netfilter/nftables control plane is explicitly a local attack vector.\nAC:L - The attacker controls both sides of the race: they choose the per-element timeout (driving when the 1 s-interval async rhash GC worker collects elements) and issue the rule-delete/abort transaction that frees the anonymous set, and can retry the loop indefinitely until the batched GC work lands after `nft_rhash_destroy()`.\nPR:L - `nfnetlink_rcv()` requires only CAP_NET_ADMIN over the network namespace, which any unprivileged user obtains via `unshare -Urn`; nftables is fully functional per-netns, so a basic local user suffices.\nUI:N - The entire sequence \u2014 creating the table/chain/rule with the inline anonymous timeout set, adding expiring elements, and deleting the binding rule \u2014 is performed by the attacker\u0027s own process with no victim action.\nS:U - The use-after-free corrupts kernel heap state within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stale GC batch reads freed `nft_rhash_elem` memory (keys hashed by `rhashtable_remove_fast()`, extension data dereferenced by `nft_setelem_data_deactivate()`), which the attacker can reallocate and spray, yielding a kernel-memory disclosure primitive and leaking kernel pointers.\nI:H - `nft_setelem_remove()` performs rhashtable unlink writes into a freed bucket table and freed nodes, `nft_use_dec()` decrements refcounts inside reallocated objects, and the elements are later destroyed a second time \u2014 a write/decrement/double-free primitive of the class routinely leveraged for nftables local privilege escalation.\nA:H - Operating on freed elements and a destroyed rhashtable reliably produces slab corruption, refcount underflow warnings, and kernel oops/panic, and the attacker can trigger it repeatedly."

"value": "AV:L - The vulnerable configuration is created and destroyed through the nfnetlink/nf_tables netlink interface (NFT_MSG_NEWSET/NEWSETELEM/DELRULE), which requires a local socket on the system. Netfilter/nftables control plane is explicitly a local attack vector.\nAC:L - The attacker controls both sides of the race: they choose the per-element timeout (driving when the 1 s-interval async rhash GC worker collects elements) and issue the rule-delete/abort transaction that frees the anonymous set, and can retry the loop indefinitely until the batched GC work lands after `nft_rhash_destroy()`.\nPR:L - `nfnetlink_rcv()` requires only CAP_NET_ADMIN over the network namespace, which any unprivileged user obtains via `unshare -Urn`; nftables is fully functional per-netns, so a basic local user suffices.\nUI:N - The entire sequence \u2014 creating the table/chain/rule with the inline anonymous timeout set, adding expiring elements, and deleting the binding rule \u2014 is performed by the attacker\u0027s own process with no victim action.\nS:U - The use-after-free corrupts kernel heap state within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stale GC batch reads freed `nft_rhash_elem` memory (keys hashed by `rhashtable_remove_fast()`, extension data dereferenced by `nft_setelem_data_deactivate()`), which the attacker can reallocate and spray, yielding a kernel-memory disclosure primitive and leaking kernel pointers.\nI:H - `nft_setelem_remove()` performs rhashtable unlink writes into a freed bucket table and freed nodes, `nft_use_dec()` decrements refcounts inside reallocated objects, and the elements are later destroyed a second time \u2014 a write/decrement/double-free primitive of the class routinely leveraged for nftables local privilege escalation.\nA:H - Operating on freed elements and a destroyed rhashtable reliably produces slab corruption, refcount underflow warnings, and kernel oops/panic, and the attacker can trigger it repeatedly."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
