North Korea bought SU-25K in 1980s and there is no information they bought SU-25T nor SM nor any upgrade package yet we saw recently their SU-25 with laser designator along Kh-25L and Kh-29L, also if I remember correctly Kh-25L were also next to Mig-29s.
Some North Korean IL-28/H-5 were modified to launch Kh-35 cruise missiles.
It would not be surprising if Mig-29 in North Korean service was modified to do it too.
North Korea is known to be capable of producing RD-9 turbojet engine used on Mig-19 and remember that initial prototypes of SU-25 were powered by RD-9 then production models were by R-13 turbojet that was also used on Mig-21, just without afterburner.
North Korea managed to produce RD-250 rocket engine and improve it by increasing lifetime to 190 seconds that is 50% increase along gimballed nozzles like its RD-180.
70 ton Hwasong-15 intercontinental ballistic missile that by itself could put into low earth orbit 100 kilogram satellite as 120 ton Unha-3 space launch vehicle.
They successfuly tested and produced own equivalent of S-300 PMU1 / PMU2 with 30N6E phased electronically scanned array radar and 48N6 surface to air missile.
Honestly I would not be surprised if they could produce Mig-25 with Mig-31 avionics.
