A buffer overflow was addressed with improved bounds checking. This issue is fixed in watchOS 8.7, tvOS 15.6, iOS 15.6 and iPadOS 15.6, macOS Monterey 12.5. A remote user may be able to cause kernel code execution.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
