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.","published":"2026-10-07T17:16:59.000Z","lastModified":"2026-10-08T20:08:46.000Z","status":"Awaiting Analysis","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-590"],"affected":[],"epss":{"score":0.0046,"percentile":0.39588,"date":"2026-10-26","history":[{"date":"2026-10-08","score":0.00448,"percentile":0.36967}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%).
