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

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

netfilter: nftables: fix percpu memory leak at nftables_addchain()

It seems to me that percpu memory for chain stats started leaking since commit 3bc158f8d0330f0a ("netfilter: nftables: map basechain priority to hardware priority") when nftchainoffloadpriority() returned an error.
