If you own a Mac or an iOS device like an iPhone or iPad, then you’ll want to make sure you’ve the latest update installed. This is because Apple has recently pushed out updates for macOS and iOS where it will bump it to macOS 11.5.1 and iOS 14.7.1 (which also includes iPadOS), so if you haven’t updated yet, you should.
According to Apple, “An application may be able to execute arbitrary code with kernel privileges. Apple is aware of a report that this issue may have been actively exploited.” This message is shared across both the iOS and iPadOS update, suggesting that it could be the same issue affecting all three of Apple’s platforms.
We’re not sure what kind of vulnerability Apple is referring to, but as Apple says, for the sake of security they cannot disclose or discuss the issues just yet. In any case, it’s always a good idea to keep your software updated anyway.
