CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

This vulnerability is an integer overflow issue that was addressed by improving input validation in certain versions of macOS. An integer overflow occurs when a calculation exceeds the maximum size that can be stored in an integer variable, potentially leading to unexpected behavior.

In this case, the vulnerability could allow an application to cause unexpected system termination, meaning the system could crash or stop working properly.

Mitigation Strategies

To mitigate this vulnerability, update your macOS system to one of the fixed versions: macOS Sequoia 15.6, macOS Sonoma 14.7.7, or macOS Ventura 13.7.7.

Applying these updates will address the integer overflow issue by improving input validation and prevent potential unexpected system termination caused by an app.

Impact Analysis

This vulnerability can impact you by allowing an application to cause unexpected system termination on affected macOS versions. This could lead to system crashes, loss of unsaved data, and potential disruption of normal operations.
