Overview

CVE-2025-37980 is a medium-severity vulnerability. It was published on May 20, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

Technical description

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

block: fix resource leak in blk_register_queue() error path

When registering a queue fails after blk_mq_sysfs_register() is

successful but the function later encounters an error, we need

to clean up the blk_mq_sysfs resources.

Add the missing blk_mq_sysfs_unregister() call in the error path

to properly clean up these resources and prevent a memory leak.

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.
