CWE-190: Integer Overflow or Wraparound
Weakness Summary
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.

Atomicorp Research Context
Atomicorp has published CVE-specific research observations associated with this weakness category. Each linked CVE page states whether the tested request was detected or blocked and is the authoritative customer-facing finding.
The CVEs and rules shown here are selected published examples, not a complete list of Atomicorp protections. If a CWE, CVE, or rule is absent from this page, no conclusion should be drawn about whether Atomicorp protects against that weakness or attack method.
A CWE describes a class of software weakness. It does not identify one exploit request, and association with a CWE does not mean that every vulnerability or exploitation path in that category is detected or blocked.
