attacker-controlled side of the race is driven entirely through NETLINK_NETFILTER `sendmsg()` batches (`nfnetlink_rcv_batch` → `nf_tables_commit`) and the freeing side through the `delete_module()` syscall; no network, adjacent-network, or remote-peer data reaches this code.\nAC:L - The attacker keeps the global destroy workqueue permanently non-empty by looping nftables commit batches, and `nf_tables_trans_destroy_work()` holds each batch across a `synchronize_rcu()` grace period, so the window during which `__nft_release_table()` can free a still-referenced set is wide and hit reliably; no memory-layout or other attacker-uncontrollable precondition is required beyond the teardown event itself, which is accounted for under User Interaction.\nPR:L - Creating the tables, sets and pending element-destroy transactions only requires `CAP_NET_ADMIN` in the netlink socket's user namespace (`netlink_net_capable`), which any unprivileged local user obtains with `unshare -Urn`, and module removal frees tables in *every* live netns including the attacker's own.\nUI:R - The freeing side is only reached via `delete_module()`, which needs `capable(CAP_SYS_MODULE)` in the initial user namespace, so a separate privileged user or administrative automation must unload `nf_tables` for the attacker's primed race to fire.\nS:U - The use-after-free occurs on kernel slab memory and is exploited within the kernel's own security authority; no VM, hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `nft_set_elem_ext()` reads the freed set's `ops` pointer and adds `ops->elemsize` as an offset, so a reallocated slab lets the attacker aim reads at arbitrary kernel addresses and have the resulting `nft_set_ext` contents processed, yielding disclosure well beyond a bounded leak.\nI:H - The destroy path performs indirect calls through pointers read from the freed object (`set->ops->destroy(ctx, set)` in `nft_set_destroy()`, `set->exprs[i]->ops->destroy`) plus writes via `nft_set_put()`'s refcount decrement and `nft_use_dec()` through an OOB-derived pointer, giving both a write primitive and control-flow hijack potential.\nA:H - Even unweaponised, the slab use-after-free in `nf_tables_trans_destroy_work()` dereferences freed memory from a kworker context, producing a kernel oops/panic (KASAN report in the commit message) and taking the machine down." }
