Common Weakness Enumeration
CWE-401
AllowedMissing Release of Memory after Effective Lifetime
Abstraction: Variant · Status: Draft
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
2126 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-09-17 15:30 – Updated: 2025-12-10 18:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
staging: vt6655: fix some erroneous memory clean-up loops
In some initialization functions of this driver, memory is allocated with 'i' acting as an index variable and increasing from 0. The commit in "Fixes" introduces some clean-up codes in case of allocation failure, which free memory in reverse order with 'i' decreasing to 0. However, there are some problems: - The case i=0 is left out. Thus memory is leaked. - In case memory allocation fails right from the start, the memory freeing loops will start with i=-1 and invalid memory locations will be accessed.
One of these loops has been fixed in commit c8ff91535880 ("staging: vt6655: fix potential memory leak"). Fix the remaining erroneous loops.

Details
There are two Information Disclosure vulnerabilities in colord, and they lie in colord/src/cd-device-db.c and colord/src/cd-profile-db.c separately. They exist because the 'err_msg' of 'sqlite3_exec' is not releasing after use, while libxml2 emphasizes that the caller needs to release it.

GHSA-RC42-XQQ7-H58R
Vulnerability from github – Published: 2026-04-03 15:30 – Updated: 2026-04-23 21:31
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
btrfs: free pages on error in btrfs_uring_read_extent()
In this function the 'pages' object is never freed in the hopes that it is picked up by btrfs_uring_read_finished() whenever that executes in the future. But that's just the happy path. Along the way previous allocations might have gone wrong, or we might not get -EIOCBQUEUED from btrfs_encoded_read_regular_fill_pages(). In all these cases, we go to a cleanup section that frees all memory allocated by this function without assuming any deferred execution, and this also needs to happen for the 'pages' allocation.

Mitigation MIT-41
Implementation
Strategy: Libraries or Frameworks
- 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 class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Architecture and Design
Build and Compilation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
No CAPEC attack patterns related to this CWE.
