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 292

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 292 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.

Availability DoS: Crash, Exit, or Restart, DoS: Instability, DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory)
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)
Implementation Choose 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 Design Use an abstraction library to abstract away risky APIs. Not a complete solution.
Architecture and Design, Build and Compilation Consider 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; }
