Apple released an iOS 14.4 update with security fixes for three vulnerabilities, which are said to be under active attack from hackers.
The tech giant said in its security update pages for iOS 14.4 and iPadOS 14.4: The three bugs affecting iPhones and iPads may have been actively exploited.
Details of the security vulnerabilities remain scarce, and an Apple spokesperson declined to comment beyond what was stated in the consultation.
It is not known who is actively exploiting the vulnerabilities, or who might be the victim, and the company has not stated whether the attack targeted a small subset of users or whether it was a broader attack.
The report said: Apple preferred not to reveal the identity of the person who sent the error, noting that additional details will be available soon, but without saying when.
Two errors were found in the kernel of the operating system and WebKit, the browser engine that powers Safari.
And Apple notes for the kernel that there is a malicious application that may be able to raise privileges, as for WebKit, the company says: A remote attacker may be able to cause random code execution.
