Security News > 2024 > May > Apple backports fix for RTKit iOS zero-day to older iPhones
Apple has backported security patches released in March to older iPhones and iPads, fixing an iOS Kernel zero-day tagged as exploited in attacks.
Today, Apple backported the March security updates to address this security flaw on iOS 16.7.8, iPadOS 16.7.8, and macOS Ventura 13.6.7 with improved input validation.
Apple has yet to disclose who disclosed the zero-day or whether it was discovered internally, and it has provided no information on the nature of the attacks exploiting it in the wild.
Even though Apple has not released details regarding CVE-2024-23296 exploitation, iOS zero-days are commonly used in state-sponsored spyware attacks targeting high-risk individuals, including journalists, dissidents, and opposition politicians.
In January, Apple also backported patches for two WebKit zero-days, which were patched in November for newer devices.
With today's iOS 17.5 update, Apple has also added support for unwanted tracking alerts.
