CVE-2017-13715: Linux Kernel

Critical severity, CVSS 9.8. EPSS: 9.7% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 4.2, before 4.3 (fixed in 4.3)
