AlienVault OTX Malware

virtual-gpu-manager

NVIDIA Display Driver for Linux contains a vulnerability in a kernel module, where an attacker might be able to trigger a null pointer deference. A successful exploit of this vulnerability might lead to denial of service.

CVE-2025-23332 is a vulnerability identified in the NVIDIA Display Driver for Linux, specifically within the Virtual GPU (vGPU) Manager kernel module. The issue is a NULL pointer dereference (CWE-476), which occurs when the software attempts to access or dereference a pointer that is null, leading to a kernel crash. This vulnerability affects all versions of the NVIDIA vGPU Manager up to and including version 19.1. An attacker with low privileges (PR:L) and requiring user interaction (UI:R) can trigger this flaw locally (AV:L), causing a denial of service (DoS) by crashing the kernel or the vGPU service, resulting in system instability or downtime. The vulnerability does not impact confidentiality or integrity, as it does not allow data leakage or unauthorized modification. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component without affecting other system components. No public exploits are known at this time, and no patches have been linked yet, indicating that mitigation relies on vendor updates and operational controls. The vulnerability was reserved in January 2025 and published in October 2025, reflecting a recent discovery. The affected product is primarily used in virtualized environments where NVIDIA GPUs are shared among multiple virtual machines, common in cloud and enterprise data centers running Linux. The vulnerability’s exploitation requires local access and user interaction, which reduces the risk of remote attacks but still poses a threat in multi-tenant or shared environments.
