The iOS 17.0.2, iPadOS 17.0.2, and watchOS 10.0.2 are available with bug fixes related to initial device setup and data transfer.
Small operating system point updates tend to include critical security and bug fixes that can't wait for a full release. Since there isn't any sign of iOS 17.1 releasing anytime soon, Apple is updating at smaller increments.
The iOS and iPadOS releases have build number 21A351, which is up from build 21A340 released on September 21.
The updates don't have any listed CVE entries, but do address a bug related to initial device setup. The update text states that it fixes an issue that may prevent transferring data directly from another iPhone/iPad during setup.
watchOS 10.0.2 has build number 21R371, up from 21R360. It only states that it addresses bug fixes and security updates for Apple Watch Series 9 and Apple Watch Ultra 2, but likely also address data transfer issues.
Anyone running iOS 17, iPadOS 17, or watchOS 10 on the affected devices are encouraged to update as soon as is reasonable. This update should be installed before attempting a device transfer.
