Title
netfilter: nf_tables: Fix potential data-race in __nft_expr_type_get()
Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: Fix potential data-race in __nft_expr_type_get() nft_unregister_expr() can concurrent with __nft_expr_type_get(), and there is not any protection when iterate over nf_tables_expressions list in __nft_expr_type_get(). Therefore, there is potential data-race of nf_tables_expressions list entry. Use list_for_each_entry_rcu() to iterate over nf_tables_expressions list in __nft_expr_type_get(), and use rcu_read_lock() in the caller nft_expr_type_get() to protect the entire type query process.

Per kernel scoring guidance, netfilter/nftables netlink configuration is a local attack vector.\nAC:L - The attacker fully controls the reader side (unbounded NFT_MSG_NEWRULE batches in one netns) and can drive the writer side by forcing expression-module autoload from a second netns, where nf_tables_module_autoload() intentionally releases commit_mutex before request_module(); because the writer holds only the global nfnl mutex and the reader only the per-netns commit_mutex, the two run concurrently with no shared lock and the race can be retried indefinitely.\nPR:L - nfnetlink gates on netlink_net_capable(skb, CAP_NET_ADMIN), which resolves to ns_capable() against the network namespace\u0027s owning user namespace, so an ordinary unprivileged user obtains it with \"unshare -Urn\". No real root or init-namespace capability is needed.\nUI:N - The attacker performs the entire sequence \u2014 creating namespaces, issuing nftables batches, and triggering module autoload \u2014 with no action by any other user or administrator.\nS:U - The race and its consequences are confined to the kernel of the same host; there is no crossing into a different security authority such as a hypervisor or IOMMU boundary.\nC:H - Losing the RCU protection lets nft_expr_type_get() retain a pointer into module memory past free_module()\u0027s synchronize_rcu(), so type-\u003eowner, type-\u003ename, type-\u003emaxattr and type-\u003epolicy are read from freed and potentially reclaimed memory; an attacker-controlled reclaim of that module-region allocation combined with the attacker-supplied nla_policy parse yields kernel memory disclosure.\nI:H - try_module_get() performs an atomic increment through a dangling type-\u003eowner pointer, giving a write into freed memory, and type-\u003eselect_ops/type-\u003eops become indirect calls through freed module-region storage that can be reclaimed (e.g. by another module load or BPF JIT allocation), making control-flow hijack achievable.\nA:H - Dereferencing the stale nft_expr_type and the freed struct module after the module\u0027s vmalloc\u0027d memory is released causes an oops or panic, and the unsynchronized traversal of a concurrently modified list can itself derail into invalid pointers."

The vulnerable path is reached only through NETLINK_NETFILTER messages (NFT_MSG_NEWRULE/NEWSET batches) sent by a local process on the same host. Per kernel scoring guidance, netfilter/nftables netlink configuration is a local attack vector.\\nAC:L - The attacker fully controls the reader side (unbounded NFT_MSG_NEWRULE batches in one netns) and can drive the writer side by forcing expression-module autoload from a second netns, where nf_tables_module_autoload() intentionally releases commit_mutex before request_module(); because the writer holds only the global nfnl mutex and the reader only the per-netns commit_mutex, the two run concurrently with no shared lock and the race can be retried indefinitely.\\nPR:L - nfnetlink gates on netlink_net_capable(skb, CAP_NET_ADMIN), which resolves to ns_capable() against the network namespace\u0027s owning user namespace, so an ordinary unprivileged user obtains it with \\\"unshare -Urn\\\". No real root or init-namespace capability is needed.\\nUI:N - The attacker performs the entire sequence \\u2014 creating namespaces, issuing nftables batches, and triggering module autoload \\u2014 with no action by any other user or administrator.\\nS:U - The race and its consequences are confined to the kernel of the same host; there is no crossing into a different security authority such as a hypervisor or IOMMU boundary.\\nC:H - Losing the RCU protection lets nft_expr_type_get() retain a pointer into module memory past free_module()\u0027s synchronize_rcu(), so type-\u003eowner, type-\u003ename, type-\u003emaxattr and type-\u003epolicy are read from freed and potentially reclaimed memory; an attacker-controlled reclaim of that module-region allocation combined with the attacker-supplied nla_policy parse yields kernel memory disclosure.\\nI:H - try_module_get() performs an atomic increment through a dangling type-\u003eowner pointer, giving a write into freed memory, and type-\u003eselect_ops/type-\u003eops become indirect calls through freed module-region storage that can be reclaimed (e.g. by another module load or BPF JIT allocation), making control-flow hijack achievable.\\nA:H - Dereferencing the stale nft_expr_type and the freed struct module after the module\u0027s vmalloc\u0027d memory is released causes an oops or panic, and the unsynchronized traversal of a concurrently modified list can itself derail into invalid pointers.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"939109c0a8e2a006a6cc8209e262d25065f4403a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"b38a133d37fa421c8447b383d788c9cc6f5cb34c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"934e66e231cff2b18faa2c8aad0b8cec13957e05\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"0b6de00206adbbfc6373b3ae38d2a6f197987907\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"8d56bad42ac4c43c6c72ddd6a654a2628bf839c5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"a9ebf340d123ae12582210407f879d6a5a1bc25b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"01f1a678b05ade4b1248019c2dcca773aebbeb7f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ef1f7df9170dbd875ce198ba84e6ab80f6fc139e\", \"lessThan\": \"f969eb84ce482331a991079ab7a5c4dc3b7f89bf\", \"versionType\": \"git\"}], \"programFiles\": [\"net/netfilter/nf_tables_api.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3.13\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"3.13\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"4.19.313\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.19.*\"}, {\"status\": \"unaffected\", \"version\": \"5.4.275\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.216\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.157\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.88\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.29\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.8\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/netfilter/nf_tables_api.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/939109c0a8e2a006a6cc8209e262d25065f4403a\"}, {\"url\": \"https://git.kernel.org/stable/c/b38a133d37fa421c8447b383d788c9cc6f5cb34c\"}, {\"url\": \"https://git.kernel.org/stable/c/934e66e231cff2b18faa2c8aad0b8cec13957e05\"}, {\"url\": \"https://git.kernel.org/stable/c/0b6de00206adbbfc6373b3ae38d2a6f197987907\"}, {\"url\": \"https://git.kernel.org/stable/c/8d56bad42ac4c43c6c72ddd6a654a2628bf839c5\"}, {\"url\": \"https://git.kernel.org/stable/c/a9ebf340d123ae12582210407f879d6a5a1bc25b\"}, {\"url\": \"https://git.kernel.org/stable/c/01f1a678b05ade4b1248019c2dcca773aebbeb7f\"}, {\"url\": \"https://git.kernel.org/stable/c/f969eb84ce482331a991079ab7a5c4dc3b7f89bf\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnetfilter: nf_tables: Fix potential data-race in __nft_expr_type_get()\\n\\nnft_unregister_expr() can concurrent with __nft_expr_type_get(),\\nand there is not any protection when iterate over nf_tables_expressions\\nlist in __nft_expr_type_get().
