Apple has released security updates for supported iPhones, iPads and Macs after reports that a file-processing flaw may have been used against selected iPhone users. Malwarebytes Labs says installing the latest update offered through Software Update closes the weakness.
Updates now available
The fixes are included in iOS and iPadOS 26.7.1, macOS Tahoe 26.7.1 and macOS Sequoia 15.8.1. Availability depends on the device model and operating system currently installed.- On an iPhone or iPad, open Settings > General > Software Update, install the update offered and enable Automatic Updates from the same screen.
- On a Mac, open the Apple menu > System Settings > General > Software Update, then select Update Now if an update is available.
- Keep a Mac plugged in and connected to the internet while installation finishes; it may restart.
A malicious file could run code
Tracked as CVE-2026-86950, the bug affects CoreGraphics, the Apple component that handles visual content such as images and PDF files across its operating systems and apps.It is an out-of-bounds write, meaning software can write past the memory area assigned to it. Processing a specially crafted file could corrupt memory, crash the affected process or allow an attacker to run their own code.
Apple addressed the problem by improving bounds checking, which verifies that software stays within the correct memory limits.
