Unity Linux 20.1050e Security Update: kernel (UTSA-2026-101986)

medium Nessus Plugin ID 337329

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-2026-101986 advisory.

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

via_wdt: fix critical boot hang due to unnamed resource allocation

The VIA watchdog driver uses allocate_resource() to reserve a MMIO region for the watchdog control register. However, the allocated resource was not given a name, which causes the kernel resource tree to contain an entry marked as <BAD> under /proc/iomem on x86 platforms.

During boot, this unnamed resource can lead to a critical hang because subsequent resource lookups and conflict checks fail to handle the invalid entry properly.

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.
