Integrity Availability Confidentiality | Modify Memory, DoS: Crash, Exit, or Restart, Execute Unauthorized Code or Commands
注意: When the memory management functions are mismatched, the consequences may be as severe as code execution, memory corruption, or program crash. Consequences and ease of exploit will vary depending on the implementation of the routines and the object being managed. | |

描述 |
| 3D engine rendering backend performs a delete[] on a buffer that was allocated using malloc() |
潜在缓解措施
Phases : Implementation
Only call matching memory management functions. Do not mix and match routines. For example, when you allocate a buffer with malloc(), dispose of the original pointer with free().
Phases : Implementation
Phases : Architecture and Design
Phases : Architecture and Design
Use a language that provides abstractions for memory allocation and deallocation.
检测方法
Automated Dynamic Analysis
Use tools that are integrated during
compilation to insert runtime error-checking mechanisms
related to memory safety errors, such as AddressSanitizer
(ASan) for C/C++ [REF-1518] or valgrind [REF-480].
有效性 : Moderate
漏洞映射说明
依据 : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
备注 : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
