CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's netfilter component, specifically related to the handling of packet transmission recursion. The impact includes potential instability during packet processing, which could lead to performance degradation or system crashes under certain conditions. Administrators and developers managing Linux-based systems should prioritize applying the relevant updates to mitigate these risks.
Original NVD Description
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.
