The vulnerability is caused by the exposure of the UART debugging interface having a lack of authentication, authorization and access control functionality. Once the interface is soldered and connected to the attacker, they gain root privilege to the system.","published":"2026-10-29T14:17:59.000Z","lastModified":"2026-11-03T01:16:56.000Z","status":"Deferred","sourceIdentifier":"cve@mitre.org","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-306"],"affected":[],"epss":{"score":0.00345,"percentile":0.28175,"date":"2026-11-03","history":[{"date":"2026-10-30","score":0.00177,"percentile":0.07252}]},"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 (0.34%).
