Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-011170)

medium Nessus Plugin ID 308938

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-2026-011170 advisory.

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

 amdgpu/pm: prevent array underflow in vega20_odn_edit_dpm_table()

 In the PP_OD_EDIT_VDDC_CURVE case the input_index variable is capped at 2 but not checked for negative values so it results in an out of bounds read. This value comes from the user via sysfs.

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.
