Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.\n\nThe nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT.\n\nWe recommend upgrading past commit
