I asked CWGC to advise what numbers of unknown Allied airmen were buried in Dieppe War Cemetery and they advised:
Grave H. 8 Unknown Flying Officer Royal Air Force 19/08/1942
Grave K. 39 Unknown Flying Officer Royal Air Force 19/08/1942


Also there is, with no known date of death, and thus might not be related to the Dieppe landing at all.
