The kernel vulnerability is even more serious, especially when paired with the other two, since it could allow that “arbitrary code” to execute with full kernel privileges, giving it access to everything on the device. In both cases, Apple says that it is “Apple is aware of a report that this issue may have been actively exploited.” Specifically, Apple notes that both the CoreGraphics and WebKit vulnerabilities could result in “arbitrary code execution” through the processing of “maliciously crafted” PDFs or web content. This means that if you’re still running an iOS 12 device, you should install this update right away. Now it appears to be following that up with an update to address the same security issues for those devices that are still stuck on iOS 12.Īccording to Apple’s iOS 12.5.5 release notes, the patch addresses vulnerabilities in CoreGraphics, WebKit, and the iOS kernel (XNU), all of which Apple claims are vulnerable to active exploits. Last Monday, Apple released an iOS 14.8 update that was so critical that the company wasn’t even willing to wait for the impending public release of iOS 15. Even though iOS 15 can still be installed on every iPhone released in the past six years - and every new iPhone sold by Apple since early 2017 - the company is also continuing to support even older iPhone models, with important iOS updates for devices as far back as the 2013 iPhone 5s and iPad mini 2.
