Exynos chipsets contain the Samsung-designed modems with problems. Qualcomm's Snapdragon chipsets use integrated Qualcomm-designed modems (usually) that should be safe (from this vulnerability). If you still have the box or possibly a receipt, Exynos S22Us have the model number SM-S908B or SM-S908B/DS. Every other model is Snapdragon. If you just have the phone itself, try the Geekbench or CPU-Z apps. They're benchmarking apps for the most part, but they also contain pretty detailed hardware reports.
