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.
2128 vulnerabilities reference this CWE, most recent first.
GHSA-VC5J-JHXM-JH4W
Vulnerability from github – Published: 2024-07-10 09:30 – Updated: 2026-05-12 12:31In the Linux kernel, the following vulnerability has been resolved:
crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak
Using completion_done to determine whether the caller has gone away only works after a complete call. Furthermore it's still possible that the caller has not yet called wait_for_completion, resulting in another potential UAF.
Fix this by making the caller use cancel_work_sync and then freeing the memory safely.

Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-07-02 21:32In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_meta_bridge: fix stale stack leak via IIFHWADDR register
NFT_META_BRI_IIFHWADDR declares its destination register with len = ETH_ALEN (6 bytes), which the register-init tracking rounds up to two 32-bit registers (8 bytes). nft_meta_bridge_get_eval() then does memcpy(dest, br_dev->dev_addr, ETH_ALEN), writing only 6 bytes and leaving the upper 2 bytes of the second register as uninitialised nft_do_chain() stack. A downstream load of that register span leaks those stale bytes to userspace.
Zero the second register before the memcpy so the full declared span is written.

GHSA-VFR5-7CJJ-F96C
Vulnerability from github – Published: 2025-08-14 18:31 – Updated: 2025-08-14 18:31A vulnerability in the Internet Key Exchange Version 2 (IKEv2) feature of Cisco IOS Software, IOS XE Software, Secure Firewall Adaptive Security Appliance (ASA) Software, and Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a memory leak, resulting in a denial of service (DoS) condition.
This vulnerability is due to a lack of proper processing of IKEv2 packets. An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device. In the case of Cisco IOS and IOS XE Software, a successful exploit could allow the attacker to cause the device to reload unexpectedly. In the case of Cisco ASA and FTD Software, a successful exploit could allow the attacker to partially exhaust system memory, causing system instability such as being unable to establish new IKEv2 VPN sessions. A manual reboot of the device is required to recover from this condition.

Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-13 21:31In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: CGX: fix bitmap leaks
The RX/TX flow-control bitmaps (rx_fc_pfvf_bmap and tx_fc_pfvf_bmap) are allocated by cgx_lmac_init() but never freed in cgx_lmac_exit(). Unbinding and rebinding the driver therefore triggers kmemleak:
unreferenced object (size 16):
backtrace:
rvu_alloc_bitmap
cgx_probe
Free both bitmaps during teardown.

GHSA-VJ4H-MG95-PJ35
Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-06-25 21:31In the Linux kernel, the following vulnerability has been resolved:
i3c: dw: Fix memory leak in dw_i3c_master_i2c_xfers()
The dw_i3c_master_i2c_xfers() function allocates memory for the xfer structure using dw_i3c_master_alloc_xfer(). If pm_runtime_resume_and_get() fails, the function returns without freeing the allocated xfer, resulting in a memory leak.
Add a dw_i3c_master_free_xfer() call to the error path to ensure the allocated memory is properly freed.
Compile tested only. Issue found using a prototype static analysis tool and code review.

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.
