Technical description

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: Fix a memory leak in nf_tables_updchain

If nft_netdev_register_hooks() fails, the memory associated with

nft_stats is not freed, causing a memory leak.

This patch fixes it by moving nft_stats_alloc() down after

nft_netdev_register_hooks() succeeds.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
