Preview at WWDC likely in June, followed by September launch.
Apple Releases iOS 11.2.2 With Security Fixes to Address Spectre Vulnerability
The iOS 11.2.2 update can be downloaded for free on all eligible devices over-the-air in the Settings app. To access the update, go to Settings --> General --> Software Update.
The iOS 11.2.2 includes further fixes for the "Meltdown" and "Spectre" vulnerabilities that came to light last week. Meltdown and Spectre are serious hardware-based vulnerabilities that take advantage of the speculative execution mechanism of a CPU, allowing hackers to gain access to sensitive information.
While Meltdown was addressed in the iOS 11.2 update, Apple said it would introduce a mitigation for Spectre early this week. There is no hardware fix for Spectre, so Apple is addressing the vulnerability using Safari-based software workarounds. From Apple's security support document:
Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generationFor more on iOS 11 and its updates, make sure to check out our iOS 11 roundup.
Description: iOS 11.2.2 includes security improvements to Safari and WebKit to mitigate the effects of Spectre (CVE-2017-5753 and CVE-2017-5715).
