They can transit MY but cannot land.
So I imagine Air India Express has to check for onward tix and docs (including the PCR/Nucleic Acid test) to final destination, unless they want to attract fines from Malaysia.
Then KA checks again at KUL, before the pax can proceed to HKG. Otherwise KA can toss these pax back at KUL to deal with.
