SAS Flight Cancellations: How Long Could They Last?

Had bought tickets for a roundtrip from Cincinnati to Oslo for the last week of September. Woke up this morning to see news of SAS pilots striking and the airline facing imminent bankruptcy. Also the main flight in question was cancelled today so I take that as a red flag that future flights of that number may be cancelled too.

Is there a risk of my flights being cancelled between now and late September, or being stranded in one country or the other due to said cancellations? And if so, are there alternative flights to get there assuming I am refunded and can get something else?
