Re: [PATCH v5 0/3] MR8834: server: Use process_vm_writev / process_vm_readv instead of ptrace when available.

[Paul Gofman (＠gofman)]

If I have to guess, this part looks suspicious:
```
            ret = mach_vm_region( process_port, &region_address, &region_size, VM_REGION_BASIC_INFO_64,
                     (vm_region_info_t)&info, &info_count, &object_name );
```
((vm_region_info_t)&info). That seems like the parameter which address on stack is below our 'written' (so writing past it can do this), and it is suspiciously casted.
