However, the returned ACPI object is owned by the caller and is never freed after use, so each successful query leaks the _DSM result object. The code also assumes that the returned object is a buffer with at least one byte. A malformed firmware response can return a different object type or an empty buffer, and the direct ret->buffer.pointer dereference can then access an invalid pointer. Use the typed _DSM helper, validate that the returned buffer contains at least one byte, and free the ACPI object after reading it.
