名称: Mismatched Memory Management Routines

The product attempts to return a memory resource to the system, but it calls a release function that is not compatible with the function that was originally used to allocate that resource.

类: Memory-Unsafe (Often)
名称: C (Undetermined)
名称: C++ (Undetermined)

常见后果

影响范围 影响 可能性
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.

参考资料 描述

CVE-2025-11015

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.
