As far as my testing shows, only the SystemExtendedProcessInformation stub is
necessary. I've added to Staging.

just for the info: this page suggests  
https://processhacker.sourceforge.io/doc/ntexapi_8h_source.html:

1261  SystemExtendedProcessInformation, // q: SYSTEM_PROCESS_INFORMATION

i checked yesterday that the following fixes the crash for me too:

@@ -2524,6 +2553,7 @@ NTSTATUS WINAPI NtQuerySystemInformation(
             else ret = STATUS_INFO_LENGTH_MISMATCH;
         }
         break;
+    case SystemExtendedProcessInformation:
     case SystemProcessInformation:
         {
             SYSTEM_PROCESS_INFORMATION* spi = SystemInformation;

No clue if it`s better/worse, just for the info
