Descriptions

This issue was addressed with improved checks. This issue is fixed in tvOS 16, iOS 16, watchOS 9. An app may be able to execute arbitrary code with kernel privileges.

Este problema se solucionó con controles mejorados. Este problema se solucionó en tvOS 16, iOS 16, watchOS 9. Es posible que una aplicación pueda ejecutar código arbitrario con privilegios del kernel.

In the function AppleAVDUserClient::decodeFrameFig, a location in the decoder's IOSurface input buffer is calculated, and then bzero is called on it. The size of this IOSurface's allocation is controllable by the userspace caller, so the calculated pointer can go out of bounds, leading to memory corruption. This issue could potentially allow an unprivileged local application to escalate its privileges to the kernel.
