Oman officially has a policy of passport validity of 6 months when entering the country.

I am an EU citizen.
The flight date is within a few days, and there isn't enough time to renew the passport in time for the flight. Is there any other option? Are there any exemptions to this? Will the passport expiry date be checked before the flight or at arrival in Oman?
Any insights or help is appreciated.
Timatic agrees that your passport must be "valid for a minimum of 6 months from the arrival date".
Even if there are exceptions, you will struggle to board a flight after airlines see this. You may get lucky and they may not check, but then you may not get lucky once in Oman. Don't count on either end not checking.
I'd try to get a passport issued as fast as possible. In Germany for example, you can pay extra to get a new passport in as little as 3 days, though this is not a service every country offers.
Do keep in mind you likely also need a visa (or e-visa) to travel to Oman (you didn't specify which country, but all the EU countries I checked needed a visa). If you change passports, you should check if your visa still applies (you may need to take both old and new passport with you or even apply for a new visa/evisa).
