Overview

CVE-2026-45997 is a medium-severity vulnerability. It was published on May 27, 2026 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:

scsi: sd: fix missing put_disk() when device_add(&disk_dev) fails

If device_add(&sdkp->disk_dev) fails, put_device() runs

scsi_disk_release(), which frees the scsi_disk but leaves the gendisk

referenced. The device_add_disk() error path in sd_probe() calls

put_disk(gd); call put_disk(gd) here to mirror that cleanup.

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.
