CWE-401 在移除最后引用时对内存的释放不恰当(内存泄露) 类漏洞列表 215

CWE-401 在移除最后引用时对内存的释放不恰当(内存泄露) 类弱点 215 条 CVE 漏洞汇总,含 AI 中文分析。

CWE-401属于内存管理漏洞,指程序在内存使用完毕后未正确释放,导致资源无法回收。攻击者通常利用此缺陷通过反复分配内存耗尽系统资源,引发拒绝服务或导致程序崩溃。开发者应避免此类问题,需确保在内存生命周期结束时调用释放函数,并采用智能指针或自动内存管理工具,严格跟踪内存分配与释放状态,防止内存泄漏。

MITRE CWE 官方描述
CWE:CWE-401 Missing Release of Memory after Effective Lifetime 英文:The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.

Most memory leaks result in general product reliability problems, but if an attacker can intentionally trigger a memory leak, the attacker might be able to launch a denial of service attack (by crashing or hanging the program) or take advantage of other unexpected program behavior resulting from a l…

缓解措施 (3)
ImplementationChoose a language or tool that provides automatic memory management, or makes manual memory management less error-prone. For example, glibc in Linux provides protection against free of invalid pointers. When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391]. To help correctly and consistently manage memory when programming in C++, consider using a smart pointer…
Architecture and DesignUse an abstraction library to abstract away risky APIs. Not a complete solution.
Architecture and Design, Build and CompilationConsider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
Effectiveness: Moderate
代码示例 (1)
The following C function leaks a block of allocated memory if the call to read() does not return the expected number of bytes:
char* getBlock(int fd) { char* buf = (char*) malloc(BLOCK_SIZE); if (!buf) { return NULL; } if (read(fd, buf, BLOCK_SIZE) != BLOCK_SIZE) { return NULL; } return buf; }
