Last modified Jun 17, 2026

CVE-2017-13715 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The __skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel before 4.3 does not ensure that n_proto, ip_proto, and thoff are initialized, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a single crafted MPLS packet.. EPSS estimates a 9.65% chance of exploitation in the next 30 days.
