When _PRS buffer is copied as a template for _SRS, a string pointer for descriptor name is also copied and it becomes stale as soon as it gets de-allocated[2]. Now _CRS is used as a template for _SRS as ACPI specification suggests if it is usable. The template from _PRS is still utilized but only when _CRS is not available or broken. To avoid use-after-free the problem in this case, however, only mandatory fields are copied, optional data is removed, and structure length is adjusted accordingly.
