CVE-2025-33221
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA Display Driver for Windows and Linux contains a vulnerability in the kernel driver, where a user could cause an incorrect permission assignment for a critical resource. A successful exploit of this vulnerability might lead to data tampering and denial of service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA Display Driver for Windows and Linux contains a kernel-mode driver vulnerability where incorrect permission assignment occurs for a critical system resource, allowing a local user to potentially manipulate permissions and cause data tampering or denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if NVIDIA display driver is installedOn Windows: Open Device Manager, expand 'Display adapters' and look for NVIDIA GPU entries. On Linux: Run 'lspci | grep -i nvidia' or check /proc/driver/nvidia/versionAffected if No NVIDIA GPU/driver found means not affected by this CVE
-
Identify the installed driver versionOn Windows: Right-click NVIDIA icon in system tray, select 'Control Panel', look at 'Driver Version' under System Information, or run 'nvidia-smi' from command line. On Linux: Run 'nvidia-smi' or check 'cat /proc/driver/nvidia/version'Affected if Version cannot be determined - further investigation needed
-
Compare installed version against affected rangesCheck if version falls within any of these ranges: 535.x (affected <535.309.01 and <539.72), 580.x (affected <580.159.03 and <582.53), 595.x (affected <595.36 and <595.71.05). Note: 535 branch has two separate patch versions (535.309.01 and 539.72) covering different scenariosAffected if Installed version is within any of the affected ranges listed - system is potentially vulnerable
-
Verify kernel driver component is loadedOn Windows: Check if NVIDIA kernel driver service is running (services.msc or 'sc query nvlddmkm'). On Linux: Run 'lsmod | grep nvidia' to confirm nvidia kernel modules are loadedAffected if Kernel driver not loaded/active reduces exploitability but vulnerability still exists in driver files
-
Check driver file permissions (Windows)Navigate to C:\Windows\System32\drivers\ and check ntfs permissions on nvlddmkm.sys - verify only privileged users/system have write accessAffected if Non-privileged users have write access to driver files indicates the permission flaw may be present
System is affected if NVIDIA display driver is installed with a version falling within any of the specified affected ranges and the kernel driver component is present on the system.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped535.309.01539.72580.159.03
Apply the NVIDIA driver update containing the fix when released; prioritize patching systems with untrusted users or network-adjacent attack surfaces given the local privilege escalation potential.
535.309.01 (for 535 branch), 539.72 (for 539 branch), 580.159.03 (for 580 branch), or 582.53 (for 582 branch)
- 1. Identify the current installed NVIDIA display driver version via nvidia-smi (Linux) or Device Manager (Windows)
- 2. For driver branch 535.x: upgrade to version 535.309.01 or later
- 3. For driver branch 539.x: upgrade to version 539.72 or later
- 4. For driver branch 580.x: upgrade to version 580.159.03 or later
- 5. For driver branch 582.x: upgrade to version 582.53 or later
- 6. Download the appropriate driver from the official NVIDIA website (nvidia.com) or your system vendor
- 7. Install the new driver following standard procedures (may require administrator/root privileges)
- 8. Reboot the system to ensure the new kernel driver loads properly
