What is the Vulnerability?

The bug, tracked as CVE-2025-43300, is an out-of-bounds write issue found within the ImageIO framework. This framework is responsible for handling image files on Apple devices. An out-of-bounds write allows a threat actor to send a specially crafted malicious image through an email, message, or webpage. When your device processes this image, the attacker could potentially crash your system or even execute malicious code remotely.

• iPad mini (5th generation and later)

• Mac devices

Why is This Patch So Important?

Unlike many other vulnerabilities, Apple has confirmed that this bug has been used in "an extremely sophisticated attack against specific targeted individuals." This means the threat is not theoretical—it is real and has been actively exploited. By applying the patch, Apple has improved boundary checks to prevent these exploits. This is the sixth zero-day vulnerability Apple has fixed since the start of 2025, highlighting the continuous need for vigilance and timely updates.
