Description

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.

Affected configurations

• linux linux kernel (>= 5.3 < 5.10.146) • linux linux kernel (>= 5.11 < 5.15.71) • linux linux kernel (>= 5.16 < 5.19.12) • linux linux kernel 6.0
