While the main focus of iOS 14.7.1 may be to fix the unlock bug introduced to iPhone models with Touch ID and a paired Apple Watch, the new operating system version also includes a myriad of “important security updates,” but Apple didn't specify what kind of security changes that might include. However, it did go into detail about the big change made with macOS 11.5.1: the fix for an exploit found in the IOMobileFrameBuffer.
