Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986933)

medium Nessus Plugin ID 268057

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-2025-986933 advisory.

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

 drm/amd/pm: Update intermediate power state for SI

 Update the current state as boot state during dpm initialization.
 During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference.

 For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 (drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)).

 Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1698

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.
