Today's iOS 27 update addresses over 100 security vulnerabilities, which is a good reason to install the new software.
If you don't want to update to iOS 27 yet, Apple also released iOS 26.7 with over 80 security fixes. 75 of the fixes are shared across both updates, so iOS 26.7 addresses many of the same issues. There are multiple kernel fixes, including one that could allow a malicious app to gain root access and another that could allow for Bluetooth remote code execution. A full list of vulnerabilities can be found on Apple's site for both iOS 27 and iOS 26.7.
None of the flaws are known to have been actively exploited, but now that details have been published, devices that are not updated could be vulnerable.
Apple has been fielding an increasing number of vulnerability discoveries as AI models get better at finding bugs. Three of today's fixes are attributed to Anthropic's Claude, and OpenAI Codex Security is mentioned in Apple's additional recognition section.
