Apple has released a set of updates that it recommends all iPhone, iPad, and Mac users download as soon as possible. No, iOS 14.5 and Big Sur 11.3 have not yet come out. Instead, what we have is and macOS .
When you download them to your devices all you get is a terse explanation from Apple that they are “important.” However, the support pages marked with 9to5Mac provide more information. Both updates fix a memory corruption issue in WebKit, the engine that powers Apple’s Safari browser. The vulnerability, which was discovered by security researchers at Google and Microsoft, may have allowed malicious actors to run code on your devices using “maliciously crafted” web content.
On iOS, you can manually download an update to your iPhone or iPad by opening the Settings app, then tapping “General” followed by “Software Update”. Meanwhile, on macOS, open the System Preferences menu and click “Software Update.”
