An attacker could exploit this vulnerability by sending a crafted MPLS echo-request to an IP address on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a device reload and a DoS condition.","state":0,"publishedAt":"2026-10-07T16:14:26.107+00:00","modifiedAt":"2026-10-08T03:55:35.639+00:00","affected":[{"ecosystem":"Vendor product","name":"Cisco NX-OS
