![]() ![]() ![]() This can happen when the size of the data written is larger than the size of the allocated memory area, when the data is written to an incorrect location within the memory area, or when the program incorrectly calculates the size or location of the data to be written. It is commonly used to allow applications to move complex image decompression and draw logic into a separate process to enhance security.Īn out-of-bounds write can occur when a program writes outside the bounds of an allocated area of memory, potentially leading to a crash or arbitrary code execution. The IOSurface framework provides a framebuffer object suitable for sharing across process boundaries. IOSurfaceAccelerator is an object that manages hardware accelerated transfers/scales between IOSurfaces in the IOSurface framework. The issue that could allow an app to execute arbitrary code with kernel privileges is fixed in iOS 15.7.5 and iPadOS 15.7.5, macOS Monterey 12.6.5, iOS 16.4.1 and iPadOS 16.4.1, macOS Big Sur 11.7.6, macOS Ventura 13.3.1. The security content of iOS 16.4.1 and iPadOS 16.4.1 contains information about two vulnerabilities that Apple has been made aware of reports that these issue may have been actively exploited.ĬVE-2023-28206: an out-of-bounds write issue in IOSurfaceAccelerator was addressed with improved input validation.
