NVIDIA Windows GPU Display Driver (nvlddmkm.sys): No rate limiting in the kernel-mode scheduler: a local process floods
CVE-2020-5982NVIDIA / GPU stackcurated
Impact
No rate limiting in the kernel-mode scheduler: a local process floods it with requests and starves the GPU. On a shared node, one noisy tenant is a denial-of-service tool against everything else on the card.
Who can reach it
Any local user or container with GPU 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.
