CVE-2025-23332: 
NVIDIA Graphics Driver vulnerability analysis and mitigation

CVE-2025-23332 is a NULL Pointer Dereference vulnerability (CWE-476) in the NVIDIA Display Driver for Linux, located within a kernel module. A successful exploit could allow a local attacker to trigger a denial of service condition. The vulnerability was disclosed on October 23, 2025, and affects multiple NVIDIA GPU product lines including GeForce, RTX/Quadro/NVS, Tesla, and vGPU (Guest Driver and Virtual GPU Manager) across several driver branches. It carries a CVSS v3.1 base score of 5.0 (Medium), assigned by NVIDIA Corporation (NVD, NVIDIA Advisory).

The vulnerability is classified as CWE-476 (NULL Pointer Dereference) and resides in a kernel module of the NVIDIA Display Driver for Linux. Exploitation requires local access with low privileges and user interaction (e.g., a user must perform some action to trigger the vulnerable code path), making remote exploitation infeasible without prior access. The attack vector is local (AV:L), with low attack complexity, meaning no special conditions beyond the preconditions are needed once access is established. No public proof-of-concept code or detailed technical write-up has been identified at this time (NVD, NVIDIA Advisory).

Successful exploitation of CVE-2025-23332 results in a denial of service, likely causing a kernel panic or system crash on the affected Linux host due to the null pointer dereference in the GPU driver kernel module. There is no impact on confidentiality or integrity (C:N/I:N), and the availability impact is rated High (A:H). The scope is unchanged, meaning the impact is confined to the affected component and does not enable privilege escalation or lateral movement (NVD).

No public exploit code or in-the-wild exploitation has been reported for CVE-2025-23332. The EPSS score is extremely low at approximately 0.012%, reflecting a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Detection plugins are available via Nessus (plugin IDs 274410, 274411, 274412, 274453, 274454, 274460, 274461) (NVD, Feedly).

NVIDIA has released patched driver versions addressing CVE-2025-23332. Users should update to the following versions or later:

• GeForce / NVIDIA RTX, Quadro, NVS / Tesla (R535 branch): 535.274.02 or later
• GeForce / NVIDIA RTX, Quadro, NVS / Tesla (R570 branch): 570.195.03 or later
• GeForce / NVIDIA RTX, Quadro, NVS / Tesla (R580 branch): 580.95.05 or later
• vGPU Guest Driver (vGPU 16.x): 535.261.03 or later
• vGPU Guest Driver (vGPU 18.x): 570.172.08 or later
• vGPU Guest Driver (vGPU 19.x): 580.82.07 or later
• Virtual GPU Manager (vGPU 16.x): 535.261.04 or later
• Virtual GPU Manager (vGPU 18.x): 570.172.07 or later
• Virtual GPU Manager (vGPU 19.x): 580.82.02 or later

No configuration-based workarounds have been published; upgrading to a patched driver is the recommended remediation (NVIDIA Advisory).
