CVE-2026-24194 NVIDIA CVE debrief

A vulnerability in NVIDIA Display Driver for Linux allows local attackers to exploit improper permission handling in a kernel mode layer handler. The flaw, published 2026-05-26, carries a CVSS 3.1 score of 7.8 (HIGH) with a vector of AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. Successful exploitation could result in denial of service, privilege escalation, information disclosure, data tampering, and code execution. The vulnerability is classified under CWE-281 (Improper Preservation of Permissions). NVIDIA has published security guidance through their customer help portal. Organizations running NVIDIA Display Driver on Linux systems should monitor for driver updates from NVIDIA and apply patches when available. The local attack vector requires authenticated access, limiting exposure but maintaining significant impact potential given kernel-level access.

Who should care

Linux system administrators running NVIDIA graphics drivers, security teams managing endpoint protection for Linux workstations and servers with NVIDIA GPUs, and organizations relying on NVIDIA driver stacks for compute or display workloads.

Technical summary

The vulnerability exists in a kernel mode layer handler within NVIDIA Display Driver for Linux, where improper permission handling creates a path for authenticated local users to escalate privileges and execute arbitrary code. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates low attack complexity with no user interaction required, yielding high impacts across confidentiality, integrity, and availability. The kernel-level positioning of the flaw amplifies potential damage, as successful exploitation grants attacker capabilities equivalent to kernel execution context.

Defensive priority

high

Recommended defensive actions

  • Monitor NVIDIA security advisories for driver update availability
  • Review Linux systems running NVIDIA Display Driver for exposure
  • Apply NVIDIA driver security patches when released
  • Implement principle of least privilege to limit local attack surface
  • Monitor for anomalous kernel-level activity on affected systems
