kernel: Kernel: Privilege escalation or denial of service in nf_tables via inverted element activity check

A flaw was found in the Linux kernel's nftables component. A logic bug in nftmapcatchallactivate causes an inverted element activity check during the abort path of a failed transaction. This can lead to a use-after-free vulnerability, as catchall verdict elements may still reference a freed chain...
