As stated in Timatic, the database used by airlines:
For Pakistan
Passports and other documents accepted for entry must be valid on arrival.
For Dubai:
Passports and other documents accepted for entry issued to residents of the United Arab Emirates must be valid on arrival.
So you can use your current passport if it's valid when you arrive in Pakistan and when you return to Dubai. If it expires while you're in Pakistan, you have to renew it before returning to Dubai
