We received a message via ACARs stating that ZZZZ reported that position 5R included undocumented dry ice of 92.0 kg and a 2.2 package.  These were not on our manifest; thus this report.I assume it was an oversight by ZZZZ. I don't know why it happened; so am hesitant to infer as to why it did.
Air carrier first Officer reported the flight received an airborne ACARS notification of undocumented dry ice in the cargo compartment.
