Unity Linux 20.1070a Security Update: kernel (UTSA-2026-005734)

high Nessus Plugin ID 300948

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-2026-005734 advisory.

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

drm/msm/dp: Free resources after unregistering them

The DP component's unbind operation walks through the submodules to unregister and clean things up. But if the unbind happens because the DP controller itself is being removed, all the memory for those submodules has just been freed.

Change the order of these operations to avoid the many use-after-free that otherwise happens in this code path.

Patchwork: https://patchwork.freedesktop.org/patch/542166/

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.
