| CVE-2024-1086 | Hig | 0.64 | 7.8 | 0.28 | KEV | Jan 31, 2024 | A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can… | |
| CVE-2023-6817 | Hig | 0.51 | 7.8 | 0.00 | Dec 18, 2023 | A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet… | ||
| CVE-2023-4244 | Hig | 0.51 | 7.8 | 0.00 | Sep 6, 2023 | A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to… | ||
| CVE-2026-23231 | Hig | 0.47 | 7.8 | 0.01 | Mar 4, 2026 | In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix use-after-free in nf_tables_addchain() nf_tables_addchain() publishes the chain to table->chains via list_add_tail_rcu() (in nft_chain_add()) before registering hooks.

| CVE-2026-43452 | Hig | 0.46 | 8.2 | 0.00 | May 8, 2026 | In the Linux kernel, the following vulnerability has been resolved: netfilter: x_tables: guard option walkers against 1-byte tail reads When the last byte of options is a non-single-byte option kind, walkers that advance with i += op[i + 1] ? : 1 can read op[i + 1] past the… | ||
| CVE-2023-52925 | Med | 0.36 | 5.5 | 0.00 | Feb 5, 2025 | In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: don't fail inserts if duplicate has expired nftables selftests fail: run-tests.sh testcases/sets/0044interval_overlap_0 Expected: 0-2 . 0-3, got: W: [FAILED] … | ||

The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making… | ||
| CVE-2023-5197 | Hig | 0.00 | 7.8 | 0.00 | Sep 27, 2023 | A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free. We recommend upgrading past… |
