Unity Linux 20.1050e Security Update: kernel (UTSA-2026-102112)

medium Nessus Plugin ID 337333

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-2026-102112 advisory.

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

net: cadence: macb: Fix a possible deadlock in macb_halt_tx.

There is a situation where after THALT is set high, TGO stays high as well. Because jiffies are never updated, as we are in a context with interrupts disabled, we never exit that loop and have a deadlock.

That deadlock was noticed on a sama5d4 device that stayed locked for days.

Use retries instead of jiffies so that the timeout really works and we do not have a deadlock anymore.

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.
