Weakness (CWE)

CWE-366: Race Condition within a Thread

Base Draft

If two threads of execution use a resource simultaneously, there exists the possibility that resources may be used while invalid, in turn making the state of execution undefined.

How to prevent it (2 mitigations)

  1. Architecture and Design

    Use locking functionality. This is the recommended solution. Implement some form of locking mechanism around code which alters or reads persistent data in a multithreaded environment.

  2. Architecture and Design

    Create resource-locking validation checks. If no inherent locking mechanisms exist, use flags and signals to enforce your own blocking scheme when resources are being used by other threads of execution.
