The issue was addressed with improved memory handling. This issue is fixed in iOS 17.5 and iPadOS 17.5, tvOS 17.5, watchOS 10.5, macOS Sonoma 14.5. An app may be able to execute arbitrary code with kernel privileges.
The product manages a group of objects or resources and performs a separate memory allocation for each object, but it does not properly limit the total amount of memory that is consumed by all of the combined objects.
While the product might limit the amount of memory that is allocated in a single operation for a single object (such as a malloc of an array), if an attacker can cause multiple objects to be allocated in separate operations, then this might cause higher total memory consumption than the developer intended, leading to a denial of service.
