A vulnerability in the Linux kernel netfilter nf_tables subsystem was resolved, addressing unsafe list traversal during concurrent ruleset updates. The flaw involved the use of splice_list_rcu() to safely publish new hooks in the list, ensuring safe netlink dump list traversal via RCU. This issue affects multiple Linux kernel versions prior to 7.0.0-28.28 and related builds. The vulnerability has a CVSS 3.1 score of 7.1, indicating a medium severity with high confidentiality impact and high availability impact but no integrity impact. A patch is available and included in updated Linux kernel packages. Users should update and reboot to apply fixes, noting that kernel ABI changes require recompilation of third-party kernel modules.
