  "details" : [ "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.", "It was found that in the Linux kernel version 4.2-rc1 to 4.3-rc1, a use of uninitialized 'n_proto', 'ip_proto', and 'thoff' variables in __skb_flow_dissect() function can lead to a remote denial-of-service via malformed MPLS packet." ],
