Linux Distros Unpatched Vulnerability : CVE-2026-16313

high Nessus Plugin ID 330637

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. (CVE-2026-16313)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
