Who should care

Organizations running NVIDIA Display Driver for Linux with UVM enabled, particularly multi-user Linux environments where local unprivileged access is possible. System administrators responsible for GPU driver maintenance and security teams monitoring for local privilege escalation or denial-of-service vectors in graphics driver stacks.

Technical summary

The vulnerability exists in the Unified Virtual Memory (UVM) component of NVIDIA Display Driver for Linux. Improper input validation allows a local, unprivileged user to trigger conditions that may result in denial of service. The attack requires local access but no user interaction or elevated privileges. The changed scope (S:C) in the CVSS vector indicates the vulnerable component impacts resources beyond its security scope.

Defensive priority

HIGH

Recommended defensive actions

Monitor NVIDIA security bulletins for driver updates addressing CVE-2026-24195
Apply updated NVIDIA Display Driver for Linux versions when available from NVIDIA
Review systems running NVIDIA Display Driver for Linux for UVM module usage
Implement principle of least privilege to limit local attack surface
Monitor for anomalous UVM-related system behavior or crashes indicating potential exploitation attempts
