Escalating its response to the processor vulnerabilities revealed recently, Apple has made iOS 11.2.2 available for the iPhone and iPad, and has issued a supplementary security update for macOS High Sierra 10.13.2 to further deal with the "Meltdown" attack vector and the "Spectre" vulnerability for the first time.
Apple's release notes are sparse for the update. Users can get it through the Software Update feature of the Settings application, or install it through iTunes.
The update comes in at 75.5MB for an iPhone X, and 65.7MB on an iPhone 7 Plus.
Following the news that both Intel- and ARM-based processors can be susceptible to various hacks, Apple confirmed that all of the processors on the Mac, iPhone, and iPad were potentially vulnerable to the "Meltdown" and "Spectre" attack vectors. However, the company also declared that it had already implemented some fixes in the latest iOS and macOS releases, with more still to come.
