Arbitrary command execution as root via udev property injection in sg3_utils when sg_inq --export parses a SCSI device with a crafted name string. Affects multiple Red Hat Enterprise Linux versions shipping sg3_utils. Publicly available exploit code exists as a proof-of-concept in the upstream fix; no active exploitation has been reported.

DescriptionCVE.org

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.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
