  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/zcrypt: Fix wrong domain value verification with EP11 CPRBs\n\nThere is a wrong upper limit check for the domain value when an EP11\nCPRB is processed for sending to a crypto card. This check is only\nactive on custom device nodes but may lead to access heap memory\nbehind perms->adm when an administrative CPRB is sent.\nAdd correct limit (AP_DOMAINS = 256) checking to fix this.",
