Last modified Jun 17, 2026

CVE-2016-7039 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The IP stack in the Linux kernel through 4.8.2 allows remote attackers to cause a denial of service (stack consumption and panic) or possibly have unspecified other impact by triggering use of the GRO path for large crafted packets, as demonstrated by packets that contain only VLAN headers, a related issue to CVE-2016-8666.. EPSS estimates a 7.61% chance of exploitation in the next 30 days.
