CVE-2026-16313
HIGHSg3_utils: sg3_utils: arbitrary command execution via udev property injection in sg_inq --export
Title source: cnaDescription
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.
