Looks like "a bug" although that is debatable.
I would have no idea why you would need to INDENT XML for pretty print (are you checking manually every XML content?), but it seems that when you use INDENT, it validates the XML content (apparently not CLOB or otherwise at that point) and creates the error.
-- not an issue if you use CDATA to ignore the malformed XML bit...
select xmlserialize(content xmlelement("root", xmlelement(NOENTITYESCAPING "SOURCE_PROD_DESC", xmlcdata(mis.description)) ) as CLOB indent)
from ( select 'BBCciafia1-BB1 <F>/A/R/U/hget/51/17-140/' as description from dual ) mis ;
<root>
  <SOURCE_PROD_DESC><![CDATA[BBCciafia1-BB1 <F>/A/R/U/hget/51/17-140/]]></SOURCE_PROD_DESC>
</root>
-- no INDENT in use, not a problem
select xmlserialize(content xmlelement("root",xmlelement(NOENTITYESCAPING "SOURCE_PROD_DESC",mis.description)) as CLOB)
from ( select 'BBCciafia1-BB1 <F>/A/R/U/hget/51/17-140/' as description from dual ) mis ;
<root><SOURCE_PROD_DESC>BBCciafia1-BB1 <F>/A/R/U/hget/51/17-140/</SOURCE_PROD_DESC></root>
-- The following will give in valid XML errors
X-00225: end-element tag "SOURCE_PROD_DESC" does not match start-element tag "F".

*Action: Check if the document to be parsed is valid.
