NVIDIA vGPU Manager (vGPU plugin): The guest OS can execute privileged operations through the vGPU Manager, which

Impact

The guest OS can execute privileged operations through the vGPU Manager, which NVIDIA rates as escalation, tampering and disclosure. Privileged host operations driven from inside a tenant VM is the escape scenario, not a degraded-service scenario.

Who can reach it

Any user inside a guest VM with a vGPU on the affected host.

What to do

Upgrade the vGPU Manager on the hypervisor host to the fixed vGPU release. The host component is a kernel module inside the hypervisor, so this is a full node drain: evacuate or power off every tenant VM on the host, upgrade, reboot the host. Guest drivers must be kept within the supported version skew and updated per VM (guest reboot). No VBIOS flash, but expect a maintenance window per host and a matching hypervisor-vendor package (VMware/Citrix/KVM/Nutanix builds ship separately).
