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

  - NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode driver where a
  local user may access another process's GPU channel state due to missing authorization checks. A successful
  exploit of this vulnerability might lead to information disclosure. (CVE-2026-47603, CVE-2026-47604)

  - NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the firmware where an attacker
  could cause a null pointer dereference. A successful exploit of this vulnerability might lead to denial of
  service. (CVE-2026-47526)

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

# vcf::nvidia_gpu::filter_constraints() matches gpumodel by substring against the lowercased WMI
# Processor string, and vcf::check_version() returns the first constraint whose range the version
# falls in. The professional rows therefore match 'nvidia rtx' rather than a bare 'rtx': consumer
# boards report as 'NVIDIA GeForce RTX ...', which contains 'rtx' and would otherwise be evaluated
# against the professional fix for R615, where the vendor publishes a different GeForce fix.
# Constraint order does not prevent that on its own, because check_version() returns the first
# constraint the version satisfies. Professional boards report as 'NVIDIA RTX ...' (for example
# 'NVIDIA RTX 5000 Ada Generation Laptop GPU'), and 'nvidia rtx' never occurs inside a GeForce
# name, so the two product lines stay separated. GeForce rows remain listed first so a plain
# GeForce board is evaluated against the GeForce fix.
