CVE-2017-18218 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In drivers/net/ethernet/hisilicon/hns/hns_enet.c in the Linux kernel before 4.13, local users can cause a denial of service (use-after-free and BUG) or possibly have unspecified other impact by leveraging differences in skb handling between hns_nic_net_xmit_hw and hns_nic_net_xmit.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
