CVE-2026-16313

Published Jul 28, 2026CWE-93EPSS 0.35%

Overview

CVE-2026-16313 is a high-severity vulnerability. It was published on July 28, 2026 and has a CVSS 3.1 base score of 7.6 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.6, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

A flaw was found in sg3_utils. The sg_inq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev device database. This could allow an attacker who can present a crafted SCSI device to execute arbitrary commands as root when the device is disconnected.

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.
