Unity Linux 20.1070e Security Update: kernel (UTSA-2025-990832)
medium Nessus Plugin ID 275081
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-2025-990832 advisory.In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3
On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_*SGI*_EL1 registers is trapped to EL2.
We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?).
The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.
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.See Also
