Unity Linux 20.1070a Security Update: kernel (UTSA-2025-986397)

medium Nessus Plugin ID 268857

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-2025-986397 advisory.

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

 drm/radeon: fix a possible null pointer dereference

 In radeon_fp_native_mode(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

 The failure status of drm_cvt_mode() on the other path is checked too.

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.
