The issue was addressed with improved memory handling. This issue is fixed in iOS 16.2 and iPadOS 16.2. An app may be able to break out of its sandbox.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
