Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-151082)

high Nessus Plugin ID 378324

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-2026-151082 advisory.

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

thunderbolt: Set tb->root_switch to NULL when domain is stopped

Similarly what we do with the firmware connection manager. This makes tb_xdp_handle_request() return error to the remote host. However, we need to make sure we keep the uuid alive so that we can reply until the whole domain is released.

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.
