NVIDIA Windows GPU Display Driver (nvlddmkm.sys): Uninitialised pointer use in nvlddmkm.sys. Local denial of service

CVSS 5.5CVE-2019-5693NVIDIA / GPU stackcurated

Impact

Uninitialised pointer use in nvlddmkm.sys. Local denial of service; uninitialised-memory bugs of this shape are often better than their rating suggests.

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.
