CVE-2026-16313

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.

7.6 (High)

When sg_inq --export processes SCSI device identification data from VPD page 0x83, the SCSI name string designator (type 8) and the ATA vendor-ID subfield are printed without sanitizing embedded control characters. A crafted SCSI/USB device can embed a newline in this field, splitting sg_inq\u0027s 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 --export for SCSI device identification and act on REMOVE_CMD when a device is removed, this allows a local attacker with physical access to a USB/SCSI port to achieve arbitrary command execution as root simply by disconnecting the crafted device.\n\nExploitation requires physical access to attach the malicious device, consistent with Red Hat\u0027s Physical (AV:P) attack vector scoring. The upstream fix (udev-conforming character escaping for this field) has not yet been included in any tagged sg3_utils release; all Red Hat-shipped versions of sg3_utils in the 1.34-1.48 range are affected.",
