High [CVE-2026-16313] arbitrary command execution via udev property injection in sg_inq --export
CVE-2026-16313Source published Source updated
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. sg3_utils versions 1.34 through 1.48 contain a command injection flaw in the export_dev_ids() function of sg_inq. A crafted SCSI/USB device can embed a newline in this field, splitting sg_inq's udev KEY=VALUE output into two lines and injecting an arbitrary udev property, including REMOVE_CMD. On systems whose default udev rules invoke sg_inq…

- Remove or comment out the REMOVE_CMD rule from 50-udev-default.rules to prevent command execution on device removal. Alternatively, if automatic SCSI device identification is not required, disable the udev rule that invokes sg_inq --export on device connection.
