I believe the term "value overflow incident" may refer to a situation where a software program, typically written in a programming language like C or C++, experiences an error due to an unexpected and unintended value overflow. In these situations, a variable or data structure within the program is assigned a value that exceeds the maximum value that can be stored in that particular memory location, which can cause unpredictable or erroneous behavior.

This type of error is commonly associated with a security vulnerability called a buffer overflow, in which an attacker is able to exploit a value overflow incident to execute arbitrary code or cause a denial-of-service attack on the affected system. Value overflow incidents can be difficult to detect and correct, and can be a serious concern for software developers and security professionals.
