Last modified

CVE-2026-16313 is a high-severity vulnerability rated 7.6/10 on the CVSS scale. 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. EPSS estimates a 0.29% chance of exploitation in the next 30 days.

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.
