NVIDIA Windows GPU Display Driver (nvlddmkm.sys): NULL dereference reachable through private IOCTLs, with NVIDIA noting
CVE-2021-1115NVIDIA / GPU stackcurated
Impact
NULL dereference reachable through private IOCTLs, with NVIDIA noting the denial of service lands in a component beyond the driver itself - the failure propagates past the GPU stack.
Who can reach it
Any local unprivileged user with GPU device access on a Windows host.
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.
