"The NVIDIA GPU display driver software on the remote host is missing a security update. It is, therefore, affected by
multiple vulnerabilities:

  - NVIDIA GPU Display Driver for Windows and Linux, all versions, contains a vulnerability in the kernel mode
    layer (nvlddmkm.sys or nvidia.ko) where improper access control may lead to denial of service, information 
    disclosure, or data corruption (CVE-2021-1076).

  - NVIDIA GPU Display Driver for Windows and Linux, R450 and R460 driver branch, contains a vulnerability 
    where the software uses a reference count to manage a resource that is incorrectly updated, which may lead
    to denial of service (CVE-2021-1077).

Note that Nessus has not tested for the issue but has instead relied only on the application's self-reported version 
number.");
