NVIDIA Windows GPU Display Driver (nvlddmkm.sys): Missing authorization check in the escape handler
CVE-2021-1054NVIDIA / GPU stackcurated
Impact
Missing authorization check in the escape handler - an unprivileged caller performs an action the driver should have refused, resulting in denial of service.
Who can reach it
Any local user with GPU device access.
What to do
Install the fixed Windows GPU Display Driver branch listed in the NVIDIA bulletin. nvlddmkm.sys is a kernel driver: the swap needs a host reboot, so on a Windows GPU node this is a drain-and-reboot, not a live driver reload. No VBIOS or BMC flash involved.
