NVIDIA vGPU Manager (vGPU plugin): Guest input drives the vGPU plugin into a floating-point exception and takes the

Impact

Guest input drives the vGPU plugin into a floating-point exception and takes the shared GPU down. vGPU 12.x before 12.3, 11.x before 11.5, 8.x before 8.8.

Who can reach it

Any unprivileged user inside a guest VM with a vGPU.

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).
