Tech giant Apple has announced a “serious security vulnerability” in its iPhones, iPads and Macs, immediately recommending all users update their software to block potential hackers from intruding.

According to various reports, the company said it is “aware of a report that this issue may have been actively exploited”.

Security experts have advised users to urgently update affected devices – the iPhone 6S and later models, newer iPads, and Mac computers running macOS Monterey, reported Sky News. It also impacts some iPod models.

In a security update on its support page, Apple said one of the flaws means a malicious application “may be able to execute arbitrary code with kernel privileges” – which website TechCrunch describes as meaning full access to the device.

It said that the other – a WebKit bug – could be exploited if a vulnerable device accessed or processed “maliciously crafted web content may lead to arbitrary code execution”.

The warning to users comes ahead of its traditional September launch of the latest iPhone – expected this year to be named the iPhone 14.
