Category: CERT C++ Secure Coding Section 14 - Concurrency (CON)
Incomplete
Summary
Weaknesses in this category are related to rules in the Concurrency (CON) section of the CERT C++ Secure Coding Standard. Since not all rules map to specific weaknesses, this category may be incomplete.
Membership
| ID | Name | Description |
|---|---|---|
| CWE-362 | Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') | A race condition occurs when multiple processes or threads access a shared resource simultaneously without proper coordination, creating a timing window where the resource's state can be unexpectedly altered, leading to unpredictable behavior or security vulnerabilities. |
| CWE-366 | Race Condition within a Thread | This vulnerability occurs when two or more threads within the same application access and manipulate a shared resource (like a variable, data structure, or file) without proper synchronization. Because the threads can execute in an unpredictable order, they can corrupt the resource's state, leading to crashes, incorrect calculations, or data loss. |
| CWE-404 | Improper Resource Shutdown or Release | This vulnerability occurs when a program fails to properly close or release a system resource—like a file handle, database connection, or memory block—after it's no longer needed, preventing its reuse. |
| CWE-488 | Exposure of Data Element to Wrong Session | This vulnerability occurs when an application fails to properly isolate data between different user sessions, allowing information from one user's session to leak into another's. |
| CWE-772 | Missing Release of Resource after Effective Lifetime | This vulnerability occurs when a program fails to properly release a system resource—like memory, file handles, or network sockets—after it is no longer needed. This leads to a gradual accumulation of unused resources, known as a resource leak. |
| CWE-868 | Weaknesses Addressed by the SEI CERT C++ Coding Standard (2016 Version) | CWE entries in this view (graph) are fully or partially eliminated by following the SEI CERT C++ Coding Standard, as published in 2016. This view is no longer being actively maintained, since it statically represents the coding rules as they were in 2016. |
Vulnerability Mapping Notes
Usage: Prohibited
Reasons: Category
Rationale:
This entry is a Category. Using categories for mapping has been discouraged since 2019. Categories are informal organizational groupings of weaknesses that can help CWE users with data aggregation, navigation, and browsing. However, they are not weaknesses in themselves.
