Current code will allocate pool to hold the null char for name buffer when PrevName==NULL, but the NameSize is still 0. For this case, GetNextVariableName will return EFI_INVALID_PARAMETER to follow UEFI 2.7 spec. UEFI 2.7 spec: The VariableNameSize must not be smaller the size of the variable name string passed to GetNextVariableName() on input in the VariableName buffer. EFI_INVALID_PARAMETER Null-terminator is not found in the first VariableNameSize bytes of the input VariableName buffer. This patch is to make NameSize to be consistent with name buffer.
