In addition to large feature updates, iOS also receives small security patches that eliminate acute vulnerabilities. Users should act quickly in such cases.
Just a few days ago, Apple released an update for iOS 15, and now the next one follows. iOS 15.0.2 is supposed to close an actively exploited vulnerability in the iPhone operating system. This allows hackers to exploit a memory error for attacks – and thus take over the iPhone.
iOS 15.0.2 fixes problem with frame buffer
As usual, Apple has created a separate support page for the new update, which explains about its content. Apple received the tip for the vulnerability from an anonymous security researcher. It was subsequently with the identifier CVE-2021-30883, it has been added to the database of known vulnerabilities and susceptibilities (CVE).
According to Apple, the security hole is caused by a memory error in the “IOMobileFrameBuffer”. The frame buffer is – simply put – the part of memory that caches images that appear on the screen. Since the IOMobileFrameBuffer is an extension of the iOS kernel, hackers can gain access to it and execute malicious code.
Access to the system kernel means virtually unrestricted access to all operating system features. Apple is aware of a report that this vulnerability has been actively exploited by hackers. iOS 15.0.2 fixes the memory bug with improved memory management.

Best to install iOS 15.0.2 right away
atechbook recommends installing the update, which is just over 400 megabytes in size, as soon as possible. This will allow you to protect iPhone and iPad from attacks. The security update is available for iPhone in the form of iOS 15.0.2 and iPad in the form of iPadOS 15.0.2. It is compatible with all devices that supported iOS/iPadOS 15: iPhone 6s and newer, all iPad Pro models, iPad Air 2 and newer, iPad 5th generation and newer, iPad mini 4 and newer, and iPod touch 7th generation.
In addition, Apple also provides similar security patches for the same vulnerability in macOS 11.6, tvOS 15 and watchOS 8.0.1.
