A malformed firmware response can return a different object\ntype or an empty buffer, and the direct ret->buffer.pointer dereference\ncan then access an invalid pointer.\n\nUse the typed _DSM helper, validate that the returned buffer contains at\nleast one byte, and free the ACPI object after reading it."
