In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Fix wrong domain value verification with EP11 CPRBs There is a wrong upper limit check for the domain value when an EP11 CPRB is processed for sending to a crypto card. This check is only active on custom device nodes but may lead to access heap memory behind perms->adm when an administrative CPRB is sent. Add correct limit (AP_DOMAINS = 256) checking to fix this.
