CWE-664: Improper Control of a Resource Through its Lifetime
Improper Control of a Resource Through its Lifetime represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Other: Other
Developer Pattern
CWE-664 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.

Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- This code allocates a socket and forks each time it receives a new connection. The program does not track how many connections have been made, and it does not limit the number of connections. Because forking is a relatively expensive operation, an attacker would be able to cause the system to run out of CPU, processes, or memory by making a large number of connections. Alternatively, an attacker could consume all available connections, preventing others from accessing the system remotely.
Remediation
- Use safe APIs
- Centralize the control
- Add regression tests
- Review logs and telemetry for attempted abuse
Detection
- Automated Static Analysis: Use Static analysis tools to check for unreleased resources.
