When Apple dropped iOS 18.2 today, the headlines were mostly focused on big changes, including new Apple Intelligence features like Image Playground and Genmoji. But the quiet side of any Apple software release surrounds its security patches. iOS 18.2 is no exception: The company dropped 20 fixes for security flaws affecting iPhone running iOS 18.1.1 and older. And while none of them appear to be actively exploited at this time, they underscore the importance of updating your device as soon as possible.
Apple fixed issues with call muting, Lock Screen privacy, and malicious processing
When I scrolled through the list of fixes, a few jumped out to me in particular. First is the fix for an Audio flaw in which muting a call while its ringing might mean the mute function fails. It goes without saying that you should be able to trust the mute button when on a call, so any issue that might result in that mute button failing is concerning. Luckily, Apple says it fixed an “inconsistent user interface” to address the issue. Another concerning flaw affects VoiceOver: Via a flaw in this screen reader function, an attacker would be able to read your notifications on your Lock Screen, when normally these alerts would be hidden until your iPhone was unlocked.
There are also a number of fixes that prevent malicious apps, images, files, and web content from wreaking havoc on your device. An AppleMobileFileIntegrity flaw, for example, allows a malicious app to access your private information, while a SceneKit flaw allows a malicious file to lead to a denial of service, which could lock an authorized user out of the device.
The good news is it appears no one has been in active danger of being attacked with any of these flaws: Apple did not disclose that any have been actively exploited, which suggests malicious users either don’t know about the flaws, or don’t know how to take advantage of them. That said, now that these flaws are exposed, it’s only a matter of time before bad actors figure out how to exploit them, so updating your iPhone as soon as possible is still the smart move.
You can see the full list of flaws below:
-
AppleMobileFileIntegrity (CVE-2024-54526): A malicious app may be able to access private information. The issue was addressed with improved checks.
