| 範圍 | 影響 | 可能性 |
|---|---|---|
| Integrity Confidentiality | Modify Application Data, Read Application Data 注意：If a released resource is subsequently reused or reallocated, then an attempt to use the original resource might allow access to sensitive data that is associated with a different user or entity. | |
| Other Availability | Other, DoS: Crash, Exit, or Restart 注意：When a resource is released it might not be in an expected state, later attempts to access the resource may lead to resultant errors that may lead to a crash. |

偵測方法
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)有效性 : High
