As far as I understand, the rule that the passport must be valid for 6 months after departure is unrelated to the visa requirement. The ESTA itself is valid until the last day of validity of your passport, or up to 2 years if that comes up first. The passport, whether it’s associated with a visa or with an ESTA, must be valid for an extra 6 months after you exit the US, unless it is issued by one of the many exempt countries. Almost all ESTA countries are exempt.
Check with your US embassy to make sure.
