NVIDIA Windows GPU Display Driver (nvlddmkm.sys): Out-of-bounds read in the DeviceIoControl handler
CVE-2019-5677NVIDIA / GPU stackcurated
Impact
Out-of-bounds read in the DeviceIoControl handler - reads past the target buffer and crashes the driver.
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.
