Apple has released two security reports covering this issue but hasn't gone into detail on the nature of the exploit. It would appear to allow an attacker to potentially gain admin access to, and full control of a device.
It also confirms a report that this issue may have been actively exploited, though it doesn't go into detail about how many devices have been affected.
Affected devices include:
If you own devices older than those listed, they're likely to be no longer being supported, and at risk of being exposed to cyberthreats. Use our reviews to search for more recent models, and find out how long they'll receive support.
Apple has released a patch to secure this issue, so if you own any of the devices listed above you should search for an update and install it straight away.
Go to Settings > General > Software Update to download and install the latest software version for your device.
For Apple Macs this should be macOS Monterey 12.5.1, or look for iOS 15.6.1 or iPadOS 15.6.1 on iPhones and iPads.
We recommend you also switch Automatic Updates to On if you haven't already done so.
Apple was quick to release a patch for this issue, but it goes to underline exactly how important it is for smart devices to receive adequate support from the manufacturer to stave off threats.
Apple generally has good form in this market. It is reluctant to confirm exactly how long it will support devices for, but in the case of its iPhones, for example, it leads the line in the mobile phone market with updates typically lasting for over six years from launch.
Other brands aren't so generous - some mobile phone brands only guarantee a minimum of two years, and many smart device brands haven't confirmed update support periods with us at all.
That's why it's important to find out the update support policy for any smart device brand before you buy. Our guide to mobile phone security includes a helpful tool that allows you to search for the estimated remaining support periods for hundreds of models.
