NVIDIA GPU Display Driver (Windows nvlddmkm.sys + Linux nvidia.ko): Out-of-bounds array access in the escape handler

Impact

Out-of-bounds array access in the escape handler on Windows and Linux, giving disclosure or a crash from unprivileged local code.

Who can reach it

Any local user or GPU container with device access.

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.
