Apple on Tuesday rolled out security updates to iOS, iPadOS, macOS, tvOS, and Safari web browser to address a new zero-day vulnerability that could result in the execution of malicious code.

Tracked as CVE-2022-42856, the issue has been described by the tech giant as a type confusion issue in the WebKit browser engine that could be triggered when processing specially crafted content, leading to arbitrary code execution.

The company said it’s “aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.1.”

While details surrounding the exact nature of the attacks are unknown as yet, it’s likely that it involved a case of social engineering or a watering hole to infect the devices when visiting a rogue or legitimate-but-compromised domain via the browser.

It’s worth noting that every third-party web browser that’s available for iOS and iPadOS, including Google Chrome, Mozilla Firefox, and Microsoft Edge, and others, is required to use the WebKit rendering engine due to restrictions imposed by Apple.
