DevicePathFromTextBBTextCoverage.c function CreateDNSDeviceNode has a bug, code:
SctStrToIPv4Addr (&IpStr1, (EFI_IPv4_ADDRESS *)(DNS + sizeof (DNS_DEVICE_PATH))); DNS is a pointer, which is increased by a structure size and converted to EFI_IPv4_ADDRESS*, which will point to an unknown address. So fix it.
