Unity Linux 20.1060a Security Update: kernel (UTSA-2026-014351)

medium Nessus Plugin ID 310380

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-2026-014351 advisory.

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

HID: amd_sfh: Fix potential NULL pointer dereference

devm_add_action_or_reset() can suddenly invoke amd_mp2_pci_remove() at registration that will cause NULL pointer dereference since corresponding data is not initialized yet. The patch moves initialization of data before devm_add_action_or_reset().

Found by Linux Driver Verification project (linuxtesting.org).

[[email protected]: rebase]

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.
