Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: use list_del_rcu for netlink hooks nft_netdev_unregister_hooks and __nft_unregister_flowtable_net_hooks need to use list_del_rcu(), this list can be walked by concurrent dumpers. Add a new helper and use it consistently.

Per kernel guidance, nftables/netfilter is Local (L).\nAC:L - Exploitation is a race between hook-list removal (`list_del()` + RCU free) and concurrent RCU walkers (`nft_dump_basechain_hook_list`, flowtable dump, or packet-path `list_for_each_entry_rcu`). An attacker with CAP_NET_ADMIN can drive both sides concurrently (e.g., one thread dumping chains/flowtables while another deletes hooks or tears down the netns).\nPR:L - All nf_tables netlink operations are gated by `netlink_net_capable(skb, CAP_NET_ADMIN)` in `nfnetlink_rcv()`. CAP_NET_ADMIN is obtainable by an unprivileged user via user+network namespaces (`unshare -Urn`), not real init-namespace root.\nUI:N - No victim interaction is required; the attacker triggers hook teardown and concurrent dumps or traffic entirely through their own netlink sockets and namespace lifecycle.\nS:U - Impact is confined to kernel memory corruption and privilege escalation within the same kernel security domain; it does not inherently cross VM, container, or IOMMU boundaries.\nC:H - Using `list_del()` instead of `list_del_rcu()` on lists walked under `rcu_read_lock()` is a use-after-free/list-corruption bug; concurrent dumpers dereference `nft_hook` fields (e.g., `ifname`) after unlink/free, enabling arbitrary kernel memory read via heap grooming.\nI:H - The freed `nft_hook` kmalloc object can be reallocated and corrupted through the dangling RCU list pointers, providing a standard kernel UAF primitive exploitable for arbitrary write and control-flow hijacking.\nA:H - The race reliably causes kernel list corruption and use-after-free, leading to oops/panic during hook dumps, flowtable lookups, or netns cleanup; UAF in this path has inherent high availability impact even when not fully weaponized."
