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 · unedited
NVIDIA Display Driver for Linux contains a vulnerability where an attacker might be able to trigger a null pointer dereference. A successful exploit of this vulnerability might lead to 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 confidence

NVIDIA Display Driver for Linux contains a null pointer dereference vulnerability that can be triggered by an attacker, potentially causing the driver to crash and result in denial of service.

MitigationApply the latest NVIDIA display driver update for Linux when available, as this is a memory safety bug in the driver code that requires a vendor patch to remediate.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify NVIDIA display driver is installed
    Run `lsmod | grep nvidia` or check if `nvidia-smi` is available on the Linux system. Also check /proc/driver/nvidia/version if it exists.
    Affected if The NVIDIA kernel module is loaded or nvidia-smi responds, indicating the driver is present
  2. Retrieve installed driver version
    Execute `nvidia-smi` and note the Driver Version field, or run `cat /proc/driver/nvidia/version` to read the module version directly.
    Affected if A version number is returned, confirming the driver is loaded and active
  3. Compare version against affected ranges
    Compare the installed version number to the version ranges NVIDIA has published as affected by CVE-2025-23330. Check NVIDIA's security bulletin for the specific version list.
    Affected if The installed version falls within the version range NVIDIA has identified as vulnerable to this CVE

A system is affected if it is running a version of the NVIDIA Display Driver for Linux that falls within the version range specified by NVIDIA for this CVE.
