kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function

A flaw was found in the Netfilter subsystem in the Linux kernel. This issue occurs in the nftverdictinit function, allowing positive values as a drop error within the hook verdict, therefore, the nfhookslow function can cause a double-free vulnerability when NFDROP is issued with a drop error tha...
