"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: conntrack: fix using __this_cpu_add in preemptible\n\nCurrently in nf_conntrack_hash_check_insert(), when it fails in\nnf_ct_ext_valid_pre/post(), NF_CT_STAT_INC() will be called in the\npreemptible context, a call trace can be triggered:\n\n BUG: using __this_cpu_add() in preemptible [00000000] code: conntrack/1636\n caller is nf_conntrack_hash_check_insert+0x45/0x430 [nf_conntrack]\n Call Trace:\n <TASK>\n dump_stack_lvl+0x33/0x46\n check_preemption_disabled+0xc3/0xf0\n nf_conntrack_hash_check_insert+0x45/0x430 [nf_conntrack]\n ctnetlink_create_conntrack+0x3cd/0x4e0 [nf_conntrack_netlink]\n ctnetlink_new_conntrack+0x1c0/0x450 [nf_conntrack_netlink]\n nfnetlink_rcv_msg+0x277/0x2f0 [nfnetlink]\n netlink_rcv_skb+0x50/0x100\n nfnetlink_rcv+0x65/0x144 [nfnetlink]\n netlink_unicast+0x1ae/0x290\n netlink_sendmsg+0x257/0x4f0\n sock_sendmsg+0x5f/0x70\n\nThis patch is to fix it by changing to use NF_CT_STAT_INC_ATOMIC() for\nnf_ct_ext_valid_pre/post() check in nf_conntrack_hash_check_insert(),\nas well as nf_ct_ext_valid_post() in __nf_conntrack_confirm().\n\nNote that nf_ct_ext_valid_pre() check in __nf_conntrack_confirm() is\nsafe to use NF_CT_STAT_INC(), as it's under local_bh_disable()."
