According to Engadget, Apple released a new update called iOS 18.4.1 on Wednesday. This update fixes two dangerous security problems in iPhone and iPad devices. The update is for iPhone XS and newer phones, and many iPad models. Apple is asking everyone to update their devices right away to stay safe.
The update fixes problems in two parts of Apple’s software that handle sound: CoreAudio and Remote Participant Audio Control (RPAC). These problems could let bad people run harmful code on your device or get around security protections. The update is about 570MB in size and comes shortly after the recent iOS 18.4 update.
Let’s understand what these sound-related parts of your device actually do:
- CoreAudio is like the main sound system of your iPhone or iPad. It handles playing music, recording voice notes, and processing all sounds on your device.
- Remote Participant Audio Control (RPAC) helps manage sound during video calls or voice calls, like controlling volume or muting people.
- Both of these had memory problems that could be used by attackers to harm your device.
One of the security problems could allow something called “code execution.” Think of this like someone sneaking into your house and being able to touch all your things. Here’s why this is dangerous:
- It lets attackers run their own harmful programs on your device
- They could steal your personal information like photos or passwords
- They might install hidden software to spy on what you do
- Your device could stop working properly
The other problem is called a “security bypass.” This is like someone finding a way to unlock your door even when you think it’s locked. Here are some examples of what could happen:
- Attackers could get around your password protections
- They might disable important security features like two-factor authentication
- Your device’s security checks could be tricked into allowing dangerous actions
- Personal information could be stolen without you knowing
This update affects many Apple devices around the world. According to the key points:
- About 1.2 billion iPhones (iPhone XS and newer models) need this update
- Around 200 million iPads are affected (including iPad Pro, iPad Air 3rd gen+, iPad 7th gen+, and iPad mini 5th gen+)
- About 76% of recent Apple devices are already using iOS 18
To protect your device, you should update right away. Here’s how:
- Open your Settings app
- Tap on General
- Tap on Software Update
- If you see iOS 18.4.1, tap Download and Install
- Make sure your device has enough battery and is connected to Wi-Fi
Apple says this update is very important for your safety. While these attacks were probably aimed at specific people, everyone should update to keep their personal information safe. Remember, keeping your device updated is one of the best ways to protect yourself from security threats.
