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. (NVD)
