The issue was addressed with improved memory handling. This issue is fixed in iOS 16.2 and iPadOS 16.2, iOS 15.7.2 and iPadOS 15.7.2. Parsing a maliciously crafted video file may lead to unexpected system termination.
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.
