The software uses length values from device responses without validating them against actual buffer sizes. An attacker can exploit this to extract up to 64KB of data from the master's memory.","published":"2026-10-26T09:16:36.000Z","lastModified":"2026-10-26T15:16:44.000Z","status":"Awaiting Analysis","sourceIdentifier":"a6d3dc9e-0591-4a13-bce7-0f5b31ff6158","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-125","CWE-195","CWE-200"],"affected":[],"epss":{"score":0.00167,"percentile":0.05896,"date":"2026-10-27","history":[{"date":"2026-10-26","score":0.00167,"percentile":0.05897}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.17%).
