The newest iOS 16.4.1 and iPadOS 16.4.1 updates cover code execution software flaws in IOSurfaceAccelerator and WebKit, suggesting a complex exploit chain was detected in the wild hitting the latest iPhone devices.

“Apple is aware of a report that this issue may have been actively exploited,” Cupertino says in a barebones advisory that credits Google and Amnesty International with reporting the issue.

The advisory documents two separate issues — CVE-2023-28205 and CVE-2023-28206 — that expose iPhones and iPads to arbitrary code execution attacks.
