CVE-2026-46324 Details
Description
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.
A vulnerability in the Linux kernel's netfilter component, specifically within the nf_tables subsystem, has been addressed. The issue arose because the functions nft_netdev_unregister_hooks and __nft_unregister_flowtable_net_hooks did not properly remove netlink hooks from their lists using the appropriate RCU-safe function. This oversight could lead to inconsistencies when the list was accessed by concurrent processes. The vulnerability has been resolved by introducing a new helper function that correctly removes the hooks and can be safely used in a concurrent context.
