{"schema":"threatline.record/2","record":{"id":"CVE-2026-76465","aliases":[],"summary":"Cisco Nexus 3000 and 9000 Series Switches MPLS OAM Remote Code Execution Vulnerability","details":"A vulnerability in the MPLS Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software for Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.\r\n\r\nThis vulnerability is due to improper validation when an affected device is processing an MPLS echo-request packet. 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.","categories":["Network & edge"],"product":"Cisco NX-OS Software","vendor":"Cisco","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-76465","source_modified_at":"2026-10-08T03:55:35.639Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Cisco NX-OS Software","vendor":"Cisco","versions":[{"version":"9.3(2)","status":"affected"},{"version":"9.3(1)","status":"affected"},{"version":"9.3(1z)","status":"affected"},{"version":"9.3(3)","status":"affected"},{"version":"9.3(4)","status":"affected"},{"version":"9.3(5)","status":"affected"},{"version":"9.3(6)","status":"affected"},{"version":"9.3(5w)","status":"affected"},{"version":"9.3(7)","status":"affected"},{"version":"9.3(7k)","status":"affected"},{"version":"9.3(7a)","status":"affected"},{"version":"9.3(8)","status":"affected"},{"version":"9.3(9)","status":"affected"},{"version":"9.3(10)","status":"affected"},{"version":"10.3(1)","status":"affected"},{"version":"10.3(2)","status":"affected"},{"version":"9.3(11)","status":"affected"},{"version":"10.3(3)","status":"affected"},{"version":"9.3(12)","status":"affected"},{"version":"10.4(1)","status":"affected"},{"version":"10.3(99w)","status":"affected"},{"version":"10.3(3w)","status":"affected"},{"version":"10.3(99x)","status":"affected"},{"version":"10.3(3o)","status":"affected"},{"version":"10.3(4)","status":"affected"},{"version":"10.3(3p)","status":"affected"},{"version":"10.3(4a)","status":"affected"},{"version":"10.4(2)","status":"affected"},{"version":"10.3(3q)","status":"affected"},{"version":"9.3(13)","status":"affected"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":9.8,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00448,"percentile":0.38001,"score_date":"2026-10-23"},"published_at":"2026-10-07T16:14:26.107Z","modified_at":"2026-10-08T03:55:35.639Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-76465","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T03:55:35.639Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-76465","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-moam-rce-uBTzYV7"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-07T00:00:00+00:00"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-08T03:55:35.639Z","content_hash":"5346ae10b4a1e6731e7f8e11099839f8680c8c83f044afff0163b5c733f7851a"}}
