CVE-2026-68410

Published Aug 10, 2026 EPSS 0.21% (11th pctl)

Overview

CVE-2026-68410 is a known-severity vulnerability. It was published on August 10, 2026.

Technical Description

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

wifi: libertas: fix memory leak in helper_firmware_cb()

helper_firmware_cb() neglects to free the single-stage firmware image

after a successful async load, leading to a memory leak in the USB

firmware-download path.

Fix this memory leak by calling release_firmware() immediately after

lbs_fw_loaded() returns.

The bug was first flagged by an experimental analysis tool we are

developing for kernel memory-management bugs while analyzing

v6.13-rc1. The tool is still under development and is not yet publicly

available. Manual inspection confirms that the bug is still present in

the current wireless tree.

An x86_64 allyesconfig build showed no new warnings. As we do not have

compatible Libertas USB hardware for exercising this firmware-download

path, no runtime testing was able to be performed.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
