Overview

CVE-2022-49949 is a medium-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

firmware_loader: Fix memory leak in firmware upload

In the case of firmware-upload, an instance of struct fw_upload is

allocated in firmware_upload_register(). This data needs to be freed

in fw_dev_release(). Create a new fw_upload_free() function in

sysfs_upload.c to handle the firmware-upload specific memory frees

and incorporate the missing kfree call for the fw_upload structure.

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.
