Unity Linux 20.1070a Security Update: kernel (UTSA-2025-988658)

medium Nessus Plugin ID 273586

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-2025-988658 advisory.

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

 drm/i915: fix a possible refcount leak in intel_dp_add_mst_connector()

 If drm_connector_init fails, intel_connector_free will be called to take care of proper free. So it is necessary to drop the refcount of port before intel_connector_free.

 (cherry picked from commit cea9ed611e85d36a05db52b6457bf584b7d969e2)

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.
