Apple has rolled out security updates to iOS, iPadOS, macOS, tvOS, watchOS, and Safari to address several security vulnerabilities, including one actively exploited zero-day bug in the wild.

Tracked as CVE-2023-38606, the shortcoming resides in the kernel and permits a malicious app to modify sensitive kernel state potentially. The company said it was addressed with improved state management.

"Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.7.1," the tech giant noted in its advisory.

It's worth noting that CVE-2023-38606 is the fourth security vulnerability discovered in connection with Operation Triangulation, a sophisticated mobile cyber espionage campaign targeting iOS devices since 2019 using a zero-click exploit chain. The other two zero-days, CVE-2023-32434 and CVE-2023-32435, were patched by Apple last month.


A third shortcoming, CVE-2022-46690, was addressed as part of security updates published in December 2022, six months prior to when the activity was publicly disclosed.

Kaspersky researchers Valentin Pashkov, Mikhail Vinogradov, Georgy Kucherin, Leonid Bezvershenko, and Boris Larin have been credited with discovering and reporting the flaw.

The updates are available for the following devices and operating systems -

With the latest round of patches, Apple has resolved a total of 11 zero-days impacting its software since the start of 2023. It also comes two weeks after the company published emergency fixes for an actively exploited bug in WebKit that could lead to arbitrary code execution (CVE-2023-37450).
