CVE-2023-41974Apple iOS and iPadOS — use-after-free to kernel code execution

A use-after-free in iOS and iPadOS, fixed in 17 and in 15.8.7, lets an app already on the device run code with kernel privileges — the step that turns a confined app into full control of the phone.

YOUR NEXT MOVE

Update to iOS and iPadOS 17 or 15.8.7 now; a commercial exploit kit carries this one, so treat devices lagging on updates as reachable.
