Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nf_tables: corrige la pérdida de memoria de percpu en nf_tables_addchain() Me parece que la memoria de percpu para las estadísticas de la cadena comenzó a perderse desde el commit 3bc158f8d0330f0a ("netfilter: nf_tables: asigna la prioridad de la cadena base al hardware prioridad") cuando nft_chain_offload_priority() devolvió un error.
