CWE-401

Allowed

Missing Release of Memory after Effective Lifetime

Abstraction: Variant · Status: Draft

API response cwe.mitre.org

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.

2175 vulnerabilities reference this CWE, most recent first.

GHSA-HRV2-R4HW-HHJC

Vulnerability from github – Published: 2025-10-22 18:30 – Updated: 2025-10-22 18:30
VLAI
Details

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

dpaa2-eth: retrieve the virtual address before dma_unmap

The TSO header was DMA unmapped before the virtual address was retrieved and then used to free the buffer. This meant that we were actually removing the DMA map and then trying to search for it to help in retrieving the virtual address. This lead to a invalid virtual address being used in the kfree call.

Fix this by calling dpaa2_iova_to_virt() prior to the dma_unmap call.

Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-12-02 03:31

Details

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

mlxsw: minimal: fix potential memory leak in mlxsw_m_linecards_init

The line cards array is not freed in the error path of mlxsw_m_linecards_init(), which can lead to a memory leak. Fix by freeing the array in the error path, thereby making the error path identical to mlxsw_m_linecards_fini().

This is because the resources allocated in jffs2_sum_init() are not released. Call jffs2_sum_exit() to release these resources to solve the problem.

GHSA-HVV3-FJWQ-P2F6

Vulnerability from github – Published: 2025-10-07 18:31 – Updated: 2026-02-03 18:30
VLAI
Details

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

hwmon: (xgene) Fix ioremap and memremap leak

Smatch reports:

drivers/hwmon/xgene-hwmon.c:757 xgene_hwmon_probe() warn: 'ctx->pcc_comm_addr' from ioremap() not released on line: 757.

This is because in drivers/hwmon/xgene-hwmon.c:701 xgene_hwmon_probe(), ioremap and memremap is not released, which may cause a leak.

To fix this, ioremap and memremap is modified to devm_ioremap and devm_memremap.

Details

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

USB: isp116x: fix memory leak with using debugfs_lookup()

When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.

Vulnerability from github – Published: 2024-07-11 18:31 – Updated: 2024-10-03 00:30
VLAI
Details

A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This memory is not properly freed in all circumstances, leading to a Denial of Service (DoS).

Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd).

Memory utilization could be monitored by:  user@host> show system memory or show system monitor memory status

This issue affects:

Junos OS:  * All versions before 21.2R3-S8,  * from 21.4 before 21.4R3-S8,

  • from 22.2 before 22.2R3-S4, 
  • from 22.3 before 22.3R3-S3, 
  • from 22.4 before 22.4R3-S3,
  • from 23.2 before 23.2R2-S1, 
  • from 23.4 before 23.4R1-S2, 23.4R2,
  • from 24.2 before 24.2R2-EVO.

Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * from 21.4 before 21.4R3-S8-EVO, * from 22.2 before 22.2R3-S4-EVO, * from 22.3 before 22.3R3-S3-EVO, * from 22.4 before 22.4R3-S3-EVO,

  • from 23.2 before 23.2R2-S1-EVO,
  • from 23.4 before 23.4R1-S2, 23.4R2,
  • from 24.2 before 24.2R2-EVO.

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.
