NVIDIA vGPU software (guest kernel-mode driver + vGPU plugin): Unvalidated length across the guest kernel-mode driver

CVE-2021-1081NVIDIA / GPU stackcurated

Impact

Unvalidated length across the guest kernel-mode driver and vGPU plugin boundary. Tenant-to-host disclosure or tampering. vGPU 12.x before 12.2, 11.x before 11.4, 8.x before 8.7.

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.
