Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992641)

high Nessus Plugin ID 280644

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-2025-992641 advisory.

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

net_sched: hfsc: Fix a potential UAF in hfsc_dequeue() too

Similarly to the previous patch, we need to safe guard hfsc_dequeue() too. But for this one, we don't have a reliable reproducer.

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.
