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.
2124 vulnerabilities reference this CWE, most recent first.
GHSA-JCJ3-VP6R-4J69
Vulnerability from github – Published: 2026-04-24 15:32 – Updated: 2026-04-29 21:31In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix device leak on probe failure
Driver core holds a reference to the USB interface and its parent USB device while the interface is bound to a driver and there is no need to take additional references unless the structures are needed after disconnect.
This driver takes a reference to the USB device during probe but does not to release it on all probe errors (e.g. when descriptor parsing fails).
Drop the redundant device reference to fix the leak, reduce cargo culting, make it easier to spot drivers where an extra reference is needed, and reduce the risk of further memory leaks.

Vulnerability from github – Published: 2026-05-28 12:30 – Updated: 2026-06-10 21:31In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure
When drm_gpuvm_resv_object_alloc() fails, the pre-allocated storage bo is not freed. Add xe_bo_free(storage) before returning the error.
xe_dma_buf_init_obj() calls xe_bo_init_locked(), which frees the bo on error. Therefore, xe_dma_buf_init_obj() must also free the bo on its own error paths. Otherwise, since xe_gem_prime_import() cannot distinguish whether the failure originated from xe_dma_buf_init_obj() or from xe_bo_init_locked(), it cannot safely decide whether the bo should be freed.
Add comments documenting the ownership semantics: on success, ownership of storage is transferred to the returned drm_gem_object; on failure, storage is freed before returning.
v2: Add comments to explain the free logic.
(cherry picked from commit 78a6c5f899f22338bbf48b44fb8950409c5a69b9)

Vulnerability from github – Published: 2025-09-16 15:32 – Updated: 2025-12-03 18:30In the Linux kernel, the following vulnerability has been resolved:
ubifs: Free memory for tmpfile name
When opening a ubifs tmpfile on an encrypted directory, function fscrypt_setup_filename allocates memory for the name that is to be stored in the directory entry, but after the name has been copied to the directory entry inode, the memory is not freed.
When running kmemleak on it we see that it is registered as a leak. The report below is triggered by a simple program 'tmpfile' just opening a tmpfile:
unreferenced object 0xffff88810178f380 (size 32): comm "tmpfile", pid 509, jiffies 4294934744 (age 1524.742s) backtrace: __kmem_cache_alloc_node __kmalloc fscrypt_setup_filename ubifs_tmpfile vfs_tmpfile path_openat

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-13 21:31In the Linux kernel, the following vulnerability has been resolved:
net/sunrpc: fix potential memory leaks in rpc_sysfs_xprt_state_change()
The issue happens on some error handling paths. When the function
fails to grab the object xprt, it simply returns 0, forgetting to
decrease the reference count of another object xps, which is
increased by rpc_sysfs_xprt_kobj_get_xprt_switch(), causing refcount
leaks. Also, the function forgets to check whether xps is valid
before using it, which may result in NULL-dereferencing issues.
Fix it by adding proper error handling code when either xprt or
xps is NULL.

int type = nla_type(nla);

Mitigation MIT-41
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
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
