Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987567)
medium Nessus Plugin ID 271018
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-2025-987567 advisory.In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3: Fix GICR_CTLR.RWP polling
It turns out that our polling of RWP is totally wrong when checking for it in the redistributors, as we test the *distributor* bit index, whereas it is a different bit number in the RDs... Oopsie boo.
This is embarassing. Not only because it is wrong, but also because it took *8 years* to notice the blunder...
Just fix the damn thing.
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
