CVE-2021-46913

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: clone set element expression template memcpy() breaks when using connlimit in set elements. Use nft_expr_clone() to initialize the connlimit expression list, otherwise connlimit garbage collector crashes when walking on the list head copy.
