{"schemaVersion":3,"id":"CVE-2026-20173","aliases":[],"status":"published","duplicateOf":null,"title":"Cisco NX-OS Software Denial of Service Vulnerability","description":"A vulnerability in Cisco NX-OS Software could allow an unauthenticated, remote attacker to exhaust system resources, causing a denial of service (DoS) condition.\n\nThis vulnerability exists because rate limiting was improperly applied to some protocols. An attacker could exploit this vulnerability by sending a high rate of UDP or TCP connections to a data plane interface on an affected device. A successful exploit could allow the attacker to cause instability to various routing and control plane protocols through some packet loss and temporary disruptions, causing a DoS condition. This DoS condition will clear without manual intervention soon after the high rate of traffic is stopped.","dates":{"published":"2026-10-07T16:12:04.505Z","modified":"2026-10-07T17:42:39.672Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.8,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.8,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.8,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00373,"percentile":0.30054,"severity":"low","asOf":"2026-10-22T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-08T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-22T00:00:00.000Z","score":0.00373,"percentile":0.30054}],"last30":[{"date":"2026-10-08T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00373,"percentile":null},{"date":"2026-10-22T00:00:00.000Z","score":0.00373,"percentile":0.30054}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-770","name":"Allocation
