Apple on Thursday confirmed a new zero-day exploit hitting older iPhones and warned that the security vulnerability also affects the macOS Catalina platform.
This is the 16th documented in-the-wild zero-day exploitation of security defects in Apple’s iOS and macOS platforms so far this year.
“Apple is aware of reports that an exploit for this issue exists in the wild,” the company said without elaborating. No other details of IOCs (indicators of compromise) were provided.
The Cupertino, Calif. software giant credited researchers at Google with intercepting the new zero-day exploit, which affects a list of older iPhones and iPads running the out-of-support iOS 13 devices like the iPad Air, the iPad mini, iPhone 5s, iPhone 6, and iPhone 6 Plus.

Apple dropped support for these older devices since the release of iOS 13 but security fixes are still being released.
The security vulnerability — CVE-2021-30869 — is described as a type confusion issue in XNU, the OS kernel used by macOS and iOS.
“A malicious application may be able to execute arbitrary code with kernel privileges, the company said in an advisory that credited multiple bug finders with the discovery — Erye Hernandez of Google Threat Analysis Group, Clément Lecigne of Google Threat Analysis Group, and Ian Beer of Google Project Zero.
The iOS 12.5.5 patch also backports the fixes for the previously documented FORCEDENTRY zero-day exploits.
