netfilter: nf_tables: fix percpu memory leak at nf_tables_addchain()

Published: 4/28/2024 Last updated: 5/11/2026 Reserved: 2/25/2024

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix percpu memory leak at nf_tables_addchain() It seems to me that percpu memory for chain stats started leaking since commit 3bc158f8d0330f0a ("netfilter: nf_tables: map basechain priority to hardware priority") when nft_chain_offload_priority() returned an error.
