Unity Linux 20.1050e Security Update: kernel (UTSA-2026-006608)

medium Nessus Plugin ID 305356

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-006608 advisory.

In the Linux kernel, the following vulnerability has been resolved:

iw_cxgb4: Fix potential NULL dereference in c4iw_fill_res_cm_id_entry()

This condition needs to match the previous if (epcp->state == LISTEN) { exactly to avoid a NULL dereference of either listen_ep or ep. The problem is that epcp has been re-assigned so just testing if (epcp->state == LISTEN) { a second time is not sufficient.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
