Common Weakness Enumeration

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.

2002 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-10-01 12:30 – Updated: 2026-01-16 21:30

Details

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

ARC: mm: fix leakage of memory allocated for PTE

Since commit d9820ff ("ARC: mm: switch pgtable_t back to struct page *") a memory leakage problem occurs. Memory allocated for page table entries not released during process termination. This issue can be reproduced by a small program that allocates a large amount of memory. After several runs, you'll see that the amount of free memory has reduced and will continue to reduce after each run. All ARC CPUs are effected by this issue. The issue was introduced since the kernel stable release v5.15-rc1.

As described in commit d9820ff after switch pgtable_t back to struct page *, a pointer to "struct page" and appropriate functions are used to allocate and free a memory page for PTEs, but the pmd_pgtable macro hasn't changed and returns the direct virtual address from the PMD (PGD) entry. Than this address used as a parameter in the __pte_free() and as a result this function couldn't release memory page allocated for PTEs.

Fix this issue by changing the pmd_pgtable macro and returning pointer to struct page.

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

rtc: class: Fix potential memleak in devm_rtc_allocate_device()

devm_rtc_allocate_device() will alloc a rtc_device first, and then run dev_set_name(). If dev_set_name() failed, the rtc_device will memleak. Move devm_add_action_or_reset() in front of dev_set_name() to prevent memleak.

Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-11 21:31
VLAI
Details

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

media: iris: gen2: Add sanity check for session stop

In iris_kill_session, inst->state is set to IRIS_INST_ERROR and session_close is executed, which will kfree(inst_hfi_gen2->packet). If stop_streaming is called afterward, it will cause a crash.

Add a NULL check for inst_hfi_gen2->packet before sendling STOP packet to firmware to fix that.

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

can: can327: can327_feed_frame_to_netdev(): fix potential skb leak when netdev is down

In can327_feed_frame_to_netdev(), it did not free the skb when netdev is down, and all callers of can327_feed_frame_to_netdev() did not free allocated skb too. That would trigger skb leak.

Fix it by adding kfree_skb() in can327_feed_frame_to_netdev() when netdev is down. Not tested, just compiled.

Vulnerability from github – Published: 2025-09-16 15:32 – Updated: 2025-12-02 21:31
VLAI
Details

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

clk: imx: clk-imxrt1050: fix memory leak in imxrt1050_clocks_probe

Use devm_of_iomap() instead of of_iomap() to automatically handle the unused ioremap region. If any error occurs, regions allocated by kzalloc() will leak, but using devm_kzalloc() instead will automatically free the memory using devm_kfree().

Also, fix error handling of hws by adding unregister_hws label, which unregisters remaining hws when iomap failed.

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

memstick/mspro_block: fix handling of read-only devices

Use set_disk_ro to propagate the read-only state to the block layer instead of checking for it in ->open and leaking a reference in case of a read-only device.

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.
