Apple was expected to introduce the new security fixes with the stable version of the iOS 26.6 update.
iOS 26 was released in September 2025
Apple released the iOS 26.5.2 update, along with the iPadOS 26.5.2 version, for select iPhone and iPad models. The new OS versions bring various security fixes that were first available with the iOS 26.6 and iPadOS 26.6 beta versions, and were expected to be generally available when those updates rolled out. However, instead of the stable version of iOS 26.6, Apple decided to introduce a new iOS 26.5.2 update, on the stable channel, stating that AI-backed malicious hacking tools were the reason for the accelerated release timeline. Available for iPhone 11 and newer models, the latest firmware version fixes an issue that may have allowed an app to cause unexpected system termination.
The Tim Cook-led tech giant told Reuters that it has accelerated the release timeline for new security updates to adapt to the new reality, as AI enables faster “development of malicious hacking tools”. The company reportedly said that it wants to reduce the time between the first public release of an update and the rollout of the stable version to users.
With this, Apple could be looking to give bad actors less time to find vulnerabilities, even before it is released to a wider user base. The company usually releases major security fixes with bigger OS updates, while reserving the smaller updates for other bug fixes, unless a new security flaw is discovered after the OS version has been rolled out. The company reportedly acknowledged that AI is reducing the time a bad actor needs to exploit a security flaw to hack devices.

Among many issues, the iOS 26.5.2 update fixes a vulnerability that allowed apps to cause system termination, along with another issue that allowed apps to also write kernel memory.
