NVIDIA Windows GPU Display Driver (nvlddmkm.sys): Resource leak in the escape handler
CVSS 5.5CVE-2019-5671NVIDIA / GPU stackcurated
Impact
Resource leak in the escape handler - a local process can exhaust kernel resources and take the display driver, and with it the node's GPUs, out 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.
