Apple has released critical security updates across iOS, iPadOS, and macOS to address a high-severity zero-day flaw (CVE-2025-43300) that has reportedly been exploited in “extremely sophisticated attacks against specific targeted individuals.”
What’s the Vulnerability?
The flaw sits in Apple’s Image I/O framework, the bit of software that processes images across iPhones, iPads, and Macs. In plain terms: attackers can hide malicious code inside an image. If a user opens that image, it could corrupt memory and potentially give hackers remote access.
Apple has released patches for:
- iOS 18.6.2 and iPadOS 18.6.2, plus iPadOS 17.7.10
- macOS Sequoia 15.6.1, macOS Sonoma 14.7.8, macOS Ventura 13.7.8
Why Businesses Should Act Now
Even though Apple hasn’t disclosed full technical details, there’s a clear pattern: flaws that start out in elite, targeted attacks often become weaponised by cybercriminals in broader campaigns.
That means these updates aren’t just for high-profile individuals – they’re essential for every business user. The longer you wait, the bigger the window of opportunity for attackers.
Broader Context: A Pattern of Rapid Zero-Day Exploits
This vulnerability marks one among several Apple has addressed in 2025. It follows patches for core system flaws (such as CVE-2025-31200 and CVE-2025-31201) used in similarly “extremely sophisticated” attacks and others patched earlier in the year.
