What is CVE-2026-16313?

A vulnerability exists in the sg3_utils package where the sg_inq command, when used with the --export option, exposes device identification data without properly sanitizing control characters within SCSI name string fields. This oversight can lead to the injection of a newline character within a device-supplied name, potentially allowing an attacker to manipulate the udev device database. If successfully executed, this flaw could enable an attacker with access to a specially crafted SCSI device to execute arbitrary commands with root privileges upon device disconnection.
