Apple has issued urgent security updates to resolve a zero-day vulnerability that has been exploited in the wild against select individuals. The flaw impacts iOS, iPadOS, and macOS, highlighting the increasing sophistication of targeted cyberattacks against Apple users.

The flaw, tracked as CVE-2025-43300, is an out-of-bounds write vulnerability located in the ImageIO framework. When processing a maliciously crafted image, the bug could lead to memory corruption and possible compromise of the device.

Apple disclosed that it is aware of reports indicating the vulnerability was actively exploited in highly targeted attacks. The company emphasized the sophistication of the campaign but did not identify the threat actors or specific victims. The vulnerability was discovered internally and addressed by implementing improved bounds checking.

Devices and Versions Affected

Apple has released fixes across its ecosystem, urging all users to update immediately. The patched versions include:

• iOS 18.6.2 / iPadOS 18.6.2 – iPhone XS and later; iPad Pro 13-inch; iPad Pro 12.9-inch (3rd gen+); iPad Pro 11-inch (1st gen+); iPad Air (3rd gen+); iPad 7th gen+; iPad mini (5th gen+).
• macOS Sequoia 15.6.1.
• iPadOS 17.7.10 – iPad Pro 12.9-inch (2nd gen), iPad Pro 10.5-inch, iPad 6th gen.
• macOS Sonoma 14.7.8.
• macOS Ventura 13.7.8.

This marks the seventh zero-day Apple has patched in 2025, with earlier fixes covering CVE-2025-24085, CVE-2025-24200, CVE-2025-24201, CVE-2025-31200, CVE-2025-31201, and CVE-2025-43200.

Additionally, in the previous month, Apple resolved a Safari zero-day (CVE-2025-6558) in an open-source component. The same flaw had also been abused in Google Chrome, highlighting how cross-platform vulnerabilities can endanger users across different browsers and operating systems.

The repeated discovery of Apple zero-days illustrates a growing trend of advanced, targeted cyberattacks. These flaws are often leveraged against high-value targets such as executives, government officials, journalists, or organizations managing sensitive data.

For individuals and businesses alike, the key takeaway is the same:

• Update devices immediately to the patched versions.
• Be vigilant when handling image files, downloads, or unknown links.
• Adopt layered cybersecurity defenses beyond vendor patches.
