On its pages for iOS/iPadOS 18.6.2 and MacOS 15.6.1, Apple described the vulnerability as one which impacts its ImageIO framework and that “processing a malicious picture file could lead to reminiscence corruption.” The corporate added that it is conscious of stories that this flaw could have been exploited within the wild in “an especially refined assault in opposition to particular focused people.” Recognized as an “out-of-bounds write challenge,” the issue was fastened by way of “improved bounds checking.”
A particularly refined assault
OK, let’s break that down for these of you who need the nitty-gritty particulars.
ImageIO is an Apple framework that lets functions learn and write most picture file codecs. This lets your gadget know tips on how to course of and show a photograph or different picture. “Processing a malicious picture file could lead to reminiscence corruption” signifies that an attacker may exploit a flaw in ImageIO by creating a picture designed to deprave your gadget’s reminiscence.
The “out-of-bounds write challenge” is the precise flaw in ImageIO, which signifies that the attacker may write information outdoors of the reminiscence reserved for a particular program. By exploiting this flaw, they might then run malicious code and even set up adware. Fixing the difficulty required Apple to arrange “improved bounds checking” to make sure that the malicious picture would not have the ability to enterprise past its assigned reminiscence.

One well-known, or notorious, firm recognized to launch all these campaigns is NSO Group. By way of its Pegasus spyware, the group has been caught a number of instances exploiting flaws on computer systems and cellular gadgets to observe the actions of focused victims.
The corporate has argued that it makes use of its Pegasus software program solely to assist official legislation enforcement our bodies go after criminals and terrorists. However Apple has sued NSO Group and been pressured to patch any exploited flaws present in its working system.
“CVE-2025-43300 may enable an attacker to set off reminiscence corruption if a person opens a malicious picture file, doubtlessly enabling malicious code execution and compromise of the iPhone,” Adam Boynton, senior safety technique supervisor of cellular gadget safety agency Jamf, stated in an e-mail to ZDNET.

“Apple has indicated that this vulnerability has been exploited in refined, focused assaults, which generally deal with people with extremely valued entry or contacts, corresponding to journalists, attorneys, activists, and authorities officers,” Boynton added. “Whereas Apple has not confirmed whether or not this particular flaw was linked to adware, related vulnerabilities in ImageIO and WebKit have beforehand been utilized in Pegasus campaigns.”
