The vulnerability is due to a race condition that occurs when the VLAN and port enter an errdisabled state, resulting in an incorrect state in the software. An attacker could exploit this vulnerability by sending frames that trigger the errdisable condition. A successful exploit could allow the attacker to cause the affected device to crash, leading to a DoS condition.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","score":6.1},"cwes":["CWE-362"],"references":["http://www.securityfocus.com/bid/105400","http://www.securitytracker.com/id/1041737","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-errdisable","http://www.securityfocus.com/bid/105400","http://www.securitytracker.com/id/1041737"],"products":["cisco:ios_xe"],"source":"nvd","synced_at":"2026-10-19T20:53:14.491561039+00:00"},"epss":{"cve":"CVE-2018-0480","score":0.00522,"percentile":0.44293,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
