Apple has disclosed critical security vulnerabilities in iPhones, iPads, and Macs that could allow attackers to take complete control of the devices.

Security experts have advised users to update affected devices as soon as possible, including the iPhone 6S and later models, newer iPads, and Mac computers running macOS Monterey. Some iPod models are also affected.

Apple added that it is "aware of a report that this issue may have been actively exploited".

Apple stated in a security update on its support page that one of the flaws allows a malicious application to "execute arbitrary code with kernel privileges," which TechCrunch interprets as full device access.

TechCrunch reported that the other - a WebKit bug - could be exploited if a vulnerable device accessed or processed "maliciously crafted web content [that] may lead to arbitrary code execution".

Apple provided no additional information on how many users were affected by the vulnerability.

The warning comes ahead of Apple's traditional September launch of the latest iPhone, which is expected to be called the iPhone 14.
