NVIDIA Windows GPU Display Driver (nvlddmkm.sys): The escape handler does not validate input buffer size
CVE-2019-5690NVIDIA / GPU stackcurated
Impact
The escape handler does not validate input buffer size. Unprivileged local caller gets a kernel memory-safety bug, rated escalation-capable.
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.
