The software performs arithmetic on message length values without proper validation, allowing negative or extremely large values to bypass safety checks. This can corrupt memory and potentially allow an attacker to execute arbitrary code on the master system.","published":"2026-10-26T09:16:36.000Z","lastModified":"2026-10-26T13:45:22.000Z","status":"Awaiting Analysis","sourceIdentifier":"a6d3dc9e-0591-4a13-bce7-0f5b31ff6158","cvss":{"version":"3.1","score":8.3,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H"},"cwe":["CWE-191","CWE-195","CWE-787"],"affected":[],"epss":{"score":0.00213,"percentile":0.11528,"date":"2026-10-27","history":[{"date":"2026-10-26","score":0.00213,"percentile":0.11512}]},"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 (0.21%).
