Apple hasn’t disclosed exactly what security issues are addressed by iOS 11.2.2, but we can expect to see details on Apple’s security page shortly. We’ll update when we learn more about the new version. For now, non-beta users can find iOS 11.2.2 for iPhone and iPad as a software update over-the-air through the Software Update section of the Settings app.
The update could relate to the recently disclosed Spectre and Meltdown flaws discovered in most computer processors including ones used in iPhones and iPads. Apple acknowledged both issues last week and said it already addressed issues that could affect iOS and macOS while risks to Safari would be addressed soon.
Update: Apple says the update is for Safari to address the Spectre vulnerability.
Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generation
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).
