Technical details
A privilege escalation vulnerability exists in the GPU kernel driver component of NVIDIA vGPU software, where insufficient access controls allow a guest virtual machine to access privileged GPU resources. The attack requires local access to the virtualized GPU and allows an attacker to escalate privileges, achieve code execution on the host, or cause denial of service. A fix is expected from NVIDIA.
