CVE-2025-23277
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 Linux and Windows contains a vulnerability in the kernel mode driver, where an attacker could access memory outside bounds permitted under normal use cases. A successful exploit of this vulnerability might lead to denial of service, data tampering, or information disclosure.
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 · high confidenceThis is an out-of-bounds memory access vulnerability in NVIDIA's kernel-mode display driver for both Linux and Windows. A local attacker could exploit improper bounds checking to read or write memory beyond allocated buffers, potentially leading to denial of service, data tampering, or information disclosure.

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.
-
Identify if NVIDIA display driver is installedWindows: Open Device Manager, expand 'Display adapters', look for NVIDIA GPU entries. Linux: Run 'lspci | grep -i nvidia' or 'nvidia-smi' to list NVIDIA hardware and driver status.Affected if No NVIDIA GPU or driver is listed - the system is not using an affected product.
-
Retrieve the installed NVIDIA driver versionWindows: Right-click NVIDIA entry in Device Manager > Properties > Driver tab > Driver Version. Linux: Run 'nvidia-smi' and check the 'Driver Version' field, or use 'cat /proc/driver/nvidia/version'.Affected if A driver version is displayed - proceed to version comparison.
-
Compare installed version against affected releasesDocument the exact version string (e.g., 550.x, 560.x) from step 2. Cross-reference with NVIDIA's official security bulletin for CVE-2025-23277 to determine if your version falls within the affected range.Affected if Your installed version is within the range listed as vulnerable in the NVIDIA security advisory for this CVE.
-
Verify the kernel-mode driver component is loadedWindows: Confirm the NVIDIA display driver is active (not disabled) in Device Manager with no yellow warning icons. Linux: Run 'lsmod | grep nvidia' to confirm nvidia kernel modules are loaded, or check 'nvidia-smi' returns driver information without errors.Affected if The kernel-mode driver is actively loaded and running - the vulnerable code path is present in memory.
A system is affected if it has an NVIDIA display driver installed with a version that falls within the vulnerable range specified in NVIDIA's security advisory for CVE-2025-23277 and the driver is actively loaded.

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.
From vendor dataApply the vendor-supplied NVIDIA Display Driver update/patch to affected systems. Since this is a kernel-mode driver, ensure proper testing in a staging environment before production deployment to verify driver compatibility.
