Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-07-21 18:30
VLAI
Details

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

ASoC: sti: use managed regmap_field allocations

The regmap_field objects allocated at player init are never freed and may leak resources if the driver is removed.

Switch to devm_regmap_field_alloc() to automatically limit the lifetime of the allocations the lifetime of the device.

Vulnerability from github – Published: 2025-09-18 15:30 – Updated: 2025-12-12 18:30
VLAI
Details

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

tracing: Free error logs of tracing instances

When a tracing instance is removed, the error messages that hold errors that occurred in the instance needs to be freed. The following reports a memory leak:

# cd /sys/kernel/tracing # mkdir instances/foo # echo 'hist:keys=x' > instances/foo/events/sched/sched_switch/trigger # cat instances/foo/error_log [ 117.404795] hist:sched:sched_switch: error: Couldn't find field Command: hist:keys=x ^ # rmdir instances/foo

Then check for memory leaks:

The problem is that the error log needs to be freed when the instance is removed.

GHSA-GQG8-WW6W-XC5V

Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-08 21:31
VLAI
Details

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

media: radio-keene: fix memory leak in error path

Fix a memory leak in usb_keene_probe(). The v4l2 control handler is initialized and controls are added, but if v4l2_device_register() or video_register_device() fails afterward, the handler was never freed, leaking memory.

Add v4l2_ctrl_handler_free() call in the err_v4l2 error path to ensure the control handler is properly freed for all error paths after it is initialized.

Vulnerability from github – Published: 2025-02-10 15:32 – Updated: 2025-04-05 00:30
VLAI
Details

A vulnerability was found in GNU Binutils 2.43 and classified as problematic. Affected by this issue is the function link_order_scan of the file ld/ldelfgen.c of the component ld. The manipulation leads to memory leak. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue. The code maintainer explains: "I'm not going to commit some of the leak fixes I've been working on to the 2.44 branch due to concern that would destabilise ld. All of the reported leaks in this bugzilla have been fixed on binutils master."

GHSA-GQVJ-VMM6-RX6C

Vulnerability from github – Published: 2024-06-21 12:31 – Updated: 2025-04-01 18:30
VLAI
Details

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

ALSA: hda/cs_dsp_ctl: Use private_free for control cleanup

Use the control private_free callback to free the associated data block. This ensures that the memory won't leak, whatever way the control gets destroyed.

The original implementation didn't actually remove the ALSA controls in hda_cs_dsp_control_remove(). It only freed the internal tracking structure. This meant it was possible to remove/unload the amp driver while leaving its ALSA controls still present in the soundcard. Obviously attempting to access them could cause segfaults or at least dereferencing stale pointers.

Vulnerability from github – Published: 2025-09-17 15:30 – Updated: 2025-12-11 15:30

Details

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

staging: pi433: 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. This requires saving off the root directory dentry to make creation of individual device subdirectories easier.

Details

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

Revert "wifi: mac80211: fix memory leak in ieee80211_if_add()"

This reverts commit 13e5afd3d773c6fc6ca2b89027befaaaa1ea7293.

ieee80211_if_free() is already called from free_netdev(ndev) because ndev->priv_destructor == ieee80211_if_free

Vulnerability from github – Published: 2025-03-10 21:31 – Updated: 2025-03-10 21:31
VLAI
Details

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

scsi: lpfc: Protect memory leak for NPIV ports sending PLOGI_RJT

There is a potential memory leak in lpfc_ignore_els_cmpl() and lpfc_els_rsp_reject() that was allocated from NPIV PLOGI_RJT (lpfc_rcv_plogi()'s login_mbox).

Check if cmdiocb->context_un.mbox was allocated in lpfc_ignore_els_cmpl(), and then free it back to phba->mbox_mem_pool along with mbox->ctx_buf for service parameters.

For lpfc_els_rsp_reject() failure, free both the ctx_buf for service parameters and the login_mbox.

5.5 (Medium)

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.
