NVIDIA vGPU software (guest kernel-mode driver + vGPU plugin): The vGPU plugin lets guest code reach privileged

Impact

The vGPU plugin lets guest code reach privileged operations it should not have, which a tenant uses to deny service on the shared GPU. vGPU 8.x before 8.4, 9.x before 9.4, 10.x before 10.3.

Who can reach it

A user inside a guest VM with a vGPU, using the guest kernel-mode driver.

What to do

Upgrade the vGPU Manager on the host and the vGPU guest driver inside each tenant VM to the fixed release. Host side is a node drain plus reboot; guest side is a per-VM driver install and reboot. Because the guest driver is inside tenant-controlled VMs, in a multi-tenant estate you cannot fully remediate the guest half yourself - the host-side upgrade is the control you own. No VBIOS flash.
