Apple has issued urgent security updates for iPhone, iPad, and macOS devices to close a zero-day vulnerability identified as CVE-2026-86950. The company confirmed that the flaw was actively exploited in sophisticated, targeted cyberattacks against selected iOS users.

The issue was discovered by Meta Product Security researchers within the CoreGraphics system component, which handles rendering of images, text, and two-dimensional graphics. According to Apple’s advisory, processing a maliciously crafted file could trigger an out-of-bounds write, potentially leading to arbitrary code execution on the affected device.

This class of memory corruption vulnerability can result in a range of consequences, from application crashes to full system compromise. Apple emphasized that the attacks were limited to specific individuals running versions of iOS prior to the newly released updates and did not constitute mass distribution of malware.

The fixes are delivered in the following releases: iOS 26.7.1, iPadOS 26.7.1, macOS Tahoe 26.7.1, and macOS Sequoia 15.8.1. Supported devices include iPhone 11 and newer models, various iPad Pro, iPad Air, standard iPad, and iPad mini variants, as well as vulnerable macOS systems.

Apple strengthened memory boundary checks to prevent exploitation. While the probability of encountering such a targeted attack remains low for most users, the company strongly recommends immediate installation of the updates because the vulnerability was already being used in the wild before public disclosure.
