Apple iOS / iPadOS 14.4 official version released: Know the fixes

The official version of Apple iOS 14.4 fixes 3 "actively exploitable" security vulnerabilities: iPhone 6s and newer models need to be upgraded

In addition to the new features of the official version of Apple iOS 14.4, iOS 14.4 also brought three significant security improvements. In a new support document announced today, Apple stated that iOS 14.4 fixes a kernel vulnerability and two WebKit vulnerabilities, which "may have been actively exploited."

First, Apple said that iOS 14.4 fixes a security hole in the kernel, affecting iPhone 6s and later, iPad Air 2 and later, iPad mini 4 and later, and iPod touch (seventh generation). The company only provided a brief detailed description.

Impact: A malicious application may elevate permissions. Apple is aware of reports that this problem may have been actively exploited.

Explanation: By improving locking, a race condition has been resolved.

iOS 14.4 also fixes two vulnerabilities in WebKit (the browser engine used by Safari), which also affects the aforementioned devices.

Impact: A remote attacker may cause arbitrary code execution. Apple is aware of reports that this issue may have been actively exploited.

Description: A logic problem has been resolved, and restrictions have been improved.

As TechCrunch pointed out, it is unusual for Apple to state that a security breach "may have been actively exploited ." The company did not provide any information about which users may become victims.

It is not yet known which attackers are actively exploiting the vulnerability. According to the consulting report, Apple did not specify whether the attack was aimed at a small number of users or a broader attack. Apple anonymizes the individual who submitted the vulnerability.

Apple said it will provide more details about these vulnerabilities in the future, but no more information is currently available. Apple said that all three vulnerabilities were reported by anonymous security researchers.

Apple iOS 14.4 can be provided to users through OTA updates in the "Settings" app. Just open the "Settings" app, select "General", and then select "Software Update". Due to the inclusion of these major security improvements, it is strongly recommended that you update as soon as possible.
