The wireless gateway service is automatically restarted after a crash, allowing repeated exploitation attempts.","published":"2026-10-06T20:17:11.000Z","lastModified":"2026-10-07T13:38:49.000Z","status":"Awaiting Analysis","sourceIdentifier":"psirt@arista.com","cvss":{"version":"4.0","score":9.4,"severity":"CRITICAL","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-121"],"affected":[],"epss":{"score":0.00246,"percentile":0.15725,"date":"2026-10-27","history":[{"date":"2026-10-07","score":0.00246,"percentile":0.14488}]},"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 (0.25%).
