Update Now: iOS 18.4.1 and macOS Sequoia 15.4.1 Address Actively Exploited Vulnerabilities

The iOS 18.4.1, iPadOS 18.4.1, macOS Sequoia 15.4.1, tvOS 18.4.1, and visionOS 2.4.1 updates that Apple released today include fixes for two major vulnerabilities, which means you should install the new software as soon as you can.

bug security vulnerability issue fix larry
According to Apple, it is aware of reports that these vulnerabilities may have been actively exploited in the wild. Apple says that the security flaws were potentially used in an "extremely sophisticated attack against specific targeted individuals."

One of the issues impacts CoreAudio, and involves a maliciously crafted audio file. Processing the audio stream in the media file could result in code execution. Apple fixed the memory corruption issue with improved bounds checking.

The other vulnerability affected pointer authentication code, and an attacker with arbitrary read and write capability could bypass the Pointer Authentication features that prevent memory from being tampered with. Apple removed the vulnerable code to prevent the exploit from working.

All of the updates are available today, and focus primarily on the security fixes. iOS 18.4.1 also addresses an issue that could prevent some wireless CarPlay setups from working properly in select vehicles.

Instead of 'this affected only a small amount/handful of users' they changed their text to sophisticated attacks against specific individuals. Classic Apple Marketing.
Sure, but this description is also arguably better for describing state sponsored targeted attacks.

I hope some day this type of updates are released as a “rapid security response”
Yeah. Whatever happened to those?

Has anyone actually ever been hacked? Still rolling on 16.7.2 on my 14 pro…. You don’t ever see any horror stories of people having their iPhone hacked because they didn’t update. At least I haven’t.
It just means you're not important

Weird: after the update, I'm no longer receiving 2-factor authentication texts. I tried rebooting, but no luck. I'm still getting regular messages though.

Never mind. I'm a dope. After the last power-down I forgot to turn my iPhone back on. Everything's working fine.
