Linux Distros Unpatched Vulnerability : CVE-2026-92382

medium Nessus Plugin ID 349322

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.

- An out-of-bounds write flaw was found in usbredir. Starting an isochronous OUT stream with a transfer count of 1 leaves the stream's single transfer buffer permanently unsubmitted, defeating the bounds check in usbredirhost_iso_packet() and allowing a usbredir peer to write past the end of the packet descriptor array on every subsequent isochronous packet. (CVE-2026-92382)

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

Solution

There is no known solution at this time.
