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.
Last updated
Overview
CWE-1176 (Inefficient CPU Computation) is a class-level software weakness catalogued by MITRE in the Common Weakness Enumeration (CWE). It describes a recurring type of mistake that can lead to exploitable security vulnerabilities.
Real-world CVEs
1 recorded CVEs are caused by CWE-1176 (Inefficient CPU Computation). The highest-severity and most recent are shown first. 0 new CWE-1176 CVEs have been recorded so far in 2026 (1 in 2025).
Common consequences
What can happen when CWE-1176 is exploited.
Reduce Performance, DoS: Resource Consumption (CPU)
Affects: 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.
How it happens
When it is introduced
Typically introduced during these phases of the software lifecycle.
Illustrative examples
Real CVEs that MITRE cites as examples of this weakness.
- CVE-2022-37734 — Chain: lexer in Java-based GraphQL server does not enforce maximum of tokens early enough (CWE-696), allowing excessive CPU consumption (CWE-1176)
