COMMON WEAKNESS ENUMERATIONIncomplete

CWE-1176

Inefficient CPU Computation

The product performs CPU computations using algorithms that are not as efficient as they could be for the needs of the developer, i.e., the computations can be optimized further.

Risk

What does successful exploitation lead to?

Reduce PerformanceDoS: Resource Consumption (CPU)

Affected security scopes: Availability

This issue can make the product perform more slowly, possibly in ways that are noticeable to the users. If an attacker can influence the amount of computation that must be performed, e.g. by triggering worst-case complexity, then this performance problem might introduce a vulnerability.

Defence

How is it prevented and fixed?

  • Follow secure coding guidelines for input handling and boundary checking.
  • Enforce strict security reviews and automated static analysis (SAST) checks.
