CVE-2026-74260
Description
AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_dup_netdev: add nf_dev_xmit_recursion*() helpers and use them
Update nft_dup and nft_fwd to use the nf_dev_xmit_recursion() helpers.
This patch also disables BH when transmitting the skb to address a
possible migration to different CPU leading to imbalanced decrementation
of the recursion counters.
This is modeled after Florian Westphal's dev_xmit_recursion*() API
available since commit 97cdcf37b57e ('net: place xmit recursion in
softnet data') according to its current state in the tree.
