Commentary
Although UEW considers this a certain Proto-Ugric item, TESz and EWUng support a Slavic origin for the Hungarian words listed here (EWUng and TESz list Slavic words like Slovak mlad' 'Jungwald'. Probably the divergent words are parallel loans from Slavic into Hungarian dialects; TESz and EWUng also mention that the words might have been borrowed via Romanian (cf. Romanian mladă 'grove, thicket').
Although TESz considers it uncertain whether malász belongs here, it is dubious that this dialectal word would rather be cognate to Khanty măγli̮ etc.
The exact borrowing routes and the relationship between the different variants in Hungarian require further research, but the word has no value in discussion of Proto-Ugric or early Hungarian phonological developments.
The origin of the Khanty word is unknown.
Conclusion
Due to the Slavic etymology for Hu malágy, the Proto-Ugric etymology has to be rejected
