Key takeaways
- Apple patched 286 bugs in iOS and macOS 27.2.
- Apple fixed an exploited CoreGraphics zero-day.
- Apple backported that fix to iOS 18.
What happened
The report comes from SecurityWeek. Apple released iOS 27.2 with patches for 286 bugs. Apple released macOS 27.2 with patches for 286 bugs. Apple identified a CoreGraphics zero-day under exploitation. Apple created a fix for that CoreGraphics zero-day. Apple backported that fix to iOS 18.
Why it matters
The exploited CoreGraphics zero-day affected older iPhones on iOS 18. Unpatched iOS 18 devices remained exposed to that zero-day before the backport. The large bug count in iOS 27.2 and macOS 27.2 increased the patch scope for affected devices.
What to do
- Install iOS 27.2 on supported devices.
- Install macOS 27.2 on supported devices.
- Install the backported fix on iOS 18 devices.
