Common Weakness Enumeration

CWE-401

Allowed

Missing 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.

2103 vulnerabilities reference this CWE, most recent first.

GHSA-433R-F7HR-HVFV

Vulnerability from github – Published: 2022-05-01 02:15 – Updated: 2022-05-01 02:15
VLAI
Details

The audit system in Linux kernel 2.6.6, and other versions before 2.6.13.4, when CONFIG_AUDITSYSCALL is enabled, uses an incorrect function to free names_cache memory, which prevents the memory from being tracked by AUDITSYSCALL code and leads to a memory leak that allows attackers to cause a denial of service (memory consumption).

In the Linux kernel, the following vulnerability has been resolved:

usb: misc: usbio: Fix URB memory leak on submit failure

When usb_submit_urb() fails in usbio_probe(), the previously allocated URB is never freed, causing a memory leak.

Fix this by jumping to err_free_urb label to properly release the URB on the error path.

Vulnerability from github – Published: 2025-05-19 22:04 – Updated: 2025-05-19 22:04
VLAI
Summary
Multer vulnerable to Denial of Service via memory leaks from unclosed streams
Details

Impact

Multer <2.0.0 is vulnerable to a resource exhaustion and memory leak issue due to improper stream handling. When the HTTP request stream emits an error, the internal busboy stream is not closed, violating Node.js stream safety guidance.

This leads to unclosed streams accumulating over time, consuming memory and file descriptors. Under sustained or repeated failure conditions, this can result in denial of service, requiring manual server restarts to recover. All users of Multer handling file uploads are potentially impacted.

Patches

Users should upgrade to 2.0.0

Workarounds

None

The reason is that put_device is not be called if cdev_device_add fails and wdd->id != 0.

watchdog_cdev_register wd_data = kzalloc [1] err = dev_set_name [2] .. err = cdev_device_add if (err) { if (wdd->id == 0) { // wdd->id != 0 .. } return err; // [1],[2] would be leaked

To fix it, call put_device in all wdd->id cases.

Vulnerability from github – Published: 2026-04-03 18:31 – Updated: 2026-05-20 15:35
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

soc: microchip: mpfs: Fix memory leak in mpfs_sys_controller_probe()

In mpfs_sys_controller_probe(), if of_get_mtd_device_by_node() fails, the function returns immediately without freeing the allocated memory for sys_controller, leading to a memory leak.

Fix this by jumping to the out_free label to ensure the memory is properly freed.

Also, consolidate the error handling for the mbox_request_channel() failure case to use the same label.

Vulnerability from github – Published: 2025-09-16 15:32 – Updated: 2025-12-02 00:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: HWS, Fix memory leak in hws_action_get_shared_stc_nic error flow

When an invalid stc_type is provided, the function allocates memory for shared_stc but jumps to unlock_and_out without freeing it, causing a memory leak.

Fix by jumping to free_shared_stc label instead to ensure proper cleanup.

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: idxd: Fix memory leak when a wq is reset

idxd_wq_disable_cleanup() which is called from the reset path for a workqueue, sets the wq type to NONE, which for other parts of the driver mean that the wq is empty (all its resources were released).

Only set the wq type to NONE after its resources are released.

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.
