NVIDIA vGPU software (guest kernel-mode driver + vGPU plugin): MULTI-TENANT ISOLATION: unvalidated input size

CVE-2021-1058NVIDIA / GPU stackcurated

Impact

MULTI-TENANT ISOLATION: unvalidated input size across the guest kernel-mode driver and vGPU plugin boundary - a tenant tampers with host-side data or crashes the shared GPU. vGPU 8.x before 8.6, 11.0 before 11.3.

Who can reach it

Any user inside a guest VM with a vGPU.

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.
