The good news for the security community is that Apple has reverted to creating a new shutdown.log file when a device is restarted instead of replacing the existing one, starting with iOS 26.2. While this doesn’t undo the damage for devices that upgraded to previous versions of iOS 26, for anyone who waited in order to preserve shutdown.log files, it’s now safe to update those devices and we recommend you do as several CVEs were patched with that release as well as the most current version, 26.3.
