NVIDIA GPU Display Driver (Windows nvlddmkm.sys + Linux nvidia.ko): Improper validation of a user-supplied pointer

Impact

Improper validation of a user-supplied pointer in the kernel-mode layer. An unprivileged local caller or GPU container crashes the driver and takes every GPU job on the node with it.

Who can reach it

Any local user or GPU container with access to the NVIDIA device nodes.

What to do

Install the fixed GPU Display Driver branch on both Windows and Linux nodes. The kernel component (nvlddmkm.sys / nvidia.ko) cannot be hot-swapped under load, so this is a node drain and reboot per host; restart the container runtime afterwards so mounted driver libraries match the kernel module. No VBIOS or BMC flash.
