Missing Release of Memory after Effective Lifetime
CWE-401
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
We track 207 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 7.6. 2 have been exploited in real attacks.
How this weakness is prevented
- 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). To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std
- 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.
