kernel: netfilter: nf_tables: release flowtable after rcu grace period on error

A flaw was found in the Linux kernel's netfilter component, specifically within the nftables subsystem. An error in releasing a flowtable after an RCU Read-Copy-Update grace period could lead to a use-after-free vulnerability. This issue could expose the flowtable to the packet path and...
