Apple continues to put out potential security fires by patching zero-day vulnerabilities, releasing an emergency update this week to patch three more recently discovered in iOS after a major software update in November already fixed three that were being actively exploited.
The newly patched bugs are part of a security update released Tuesday for iOS 14.4 and iPadOS 14.4. One bug, tracked as CVE-2021-1782, was found in the OS kernel, while the other two–CVE-2021-1870 and CVE-2021-1871–were discovered in the WebKit browser engine.
The most recent vulnerabilities apparently weren’t known when Apple released iOS 14.2 and iPadOS 14.2, a comprehensive update that patched a total of 24 vulnerabilities back in November. That update included fixes for three zero-day flaws discovered by the Google Project Zero team that were actively being exploited in the wild.
