Jumo: Insufficient entropy in PRNG may lead to root access_CVE-2025-41731

{
    "lastseen": "",
    "description": "A vulnerability was identified in the password generation algorithm when accessing the debug-interface. An unauthenticated local attacker with knowledge of the password generation timeframe might be able to brute force the password in a timely manner and thus gain root access to the device if the debug interface is still enabled.",
