Your device will restart and apply the update.
If you don't see 15.7.1 available, it means that your device supports iOS 16 or iPadOS 16, which are the latest major versions of Apple's software. You can choose to update to these versions instead, but be aware that they may have some compatibility issues with some apps or accessories. You can also choose to stay on your current version of iOS or iPadOS, but you won't receive any more security updates from Apple unless you update to iOS 16 or iPadOS 16.
<h2 Security Fixes in 15.7.1
In this section, we'll go over the security fixes that are included in 15.7.1 and explain what they mean for your device. We'll also provide a table that summarizes the affected components, the impact, and the CVE identifiers of each issue.
Apple Neural Engine
The Apple Neural Engine is a hardware component that powers machine learning and artificial intelligence features on your device, such as Face ID, Animoji, Siri, and more. It's designed to process complex tasks faster and more efficiently than the main CPU. However, a vulnerability in the Apple Neural Engine could allow an app to execute arbitrary code with kernel privileges, which means that it could access and modify any part of the system. This could result in data loss, privacy breach, or system compromise. Apple has fixed this issue by improving the validation of inputs to the Apple Neural Engine.
Audio
The audio component of iOS and iPadOS handles the sound processing and playback on your device, such as music, podcasts, calls, and more. It's also responsible for managing the audio settings and permissions for different apps. However, a bug in the audio component could lead to disclosure of user information. This means that an app could access or leak your personal data, such as your contacts, messages, photos, or location. Apple has fixed this issue by improving the handling of audio buffers.
Backup
The backup component of iOS and iPadOS allows you to create and restore backups of your device using iCloud or iTunes. It's a useful feature that helps you preserve your data and settings in case you lose or damage your device. However, a permissions issue in the backup component could allow an app to access iOS backups. This means that an app could read or modify your backup files, which could contain sensitive information such as your passwords, documents, or media. Apple has fixed this issue by improving the enforcement of backup permissions.
FaceTime
FaceTime is a video calling app that lets you communicate with other Apple users using your device's camera and microphone. It's a fun and convenient way to stay in touch with your friends and family. However, a lock screen issue in FaceTime could let a user view restricted content. This means that someone who has physical access to your device could bypass the lock screen and see your notifications, messages, or other content without entering your passcode. Apple has fixed this issue by improving the lock screen logic for FaceTime calls.
Graphics Driver
The graphics driver is a software component that controls the graphics processing unit (GPU) on your device, which is responsible for rendering images, videos, games, and more. It's designed to optimize the performance and quality of the graphics output on your device. However, a flaw in the graphics driver could also allow an app to execute arbitrary code with kernel privileges, which could have the same consequences as the Apple Neural Engine vulnerability mentioned above. Apple has fixed this issue by improving the memory management of the graphics driver.
Image Processing
The image processing component of iOS and iPadOS handles the manipulation and display of images on your device, such as photos, wallpapers, icons, and more. It's also responsible for applying filters, effects, and adjustments to your images. However, an issue in the image processing component could also allow an app to execute arbitrary code with kernel privileges, which could have the same consequences as the Apple Neural Engine and graphics driver vulnerabilities mentioned above. Apple has fixed this issue by improving the validation of image metadata.
Kernel
The kernel is the core component of iOS and iPadOS that manages the basic functions of your device, such as memory allocation, process management, security enforcement, and more. It's essentially the bridge between the hardware and the software on your device. However, a memory corruption issue in the kernel could cause unexpected system termination or arbitrary code execution, which means that your device could crash or be compromised by malicious code. Apple has fixed this issue by improving t
