CVE-2026-24192 NVIDIA CVE debrief

A heap buffer overflow vulnerability in NVIDIA Display Driver for Linux, caused by incorrect numeric type conversion, exposes affected systems to multiple high-impact attack vectors including privilege escalation and code execution. The vulnerability carries a CVSS 3.1 score of 7.8 (HIGH severity) with a local attack vector requiring low privileges but no user interaction. Published by NVIDIA PSIRT on 2026-05-26, this issue is currently undergoing analysis in the NVD. The weakness is categorized as CWE-681 (Incorrect Conversion between Numeric Types). Organizations running NVIDIA Display Driver on Linux systems should prioritize patching and implement principle of least privilege to mitigate exploitation risk.

Vendor: NVIDIA
Product: GeForce
CVSS: HIGH 7.8
CISA KEV: Not listed in stored evidence
Original CVE published: 2026-05-26
Original CVE updated: 2026-05-26
Advisory published: 2026-05-26
Advisory updated: 2026-05-26

Who should care

Linux system administrators managing workstations or servers with NVIDIA graphics hardware; security teams in organizations with developer workstations, AI/ML training nodes, or VDI environments using NVIDIA GPUs; compliance officers tracking patch SLAs for high-severity local privilege escalation vulnerabilities

Technical summary

The vulnerability stems from incorrect conversion between numeric types (CWE-681) in NVIDIA Display Driver for Linux, resulting in a heap buffer overflow condition. With CVSS 3.1 vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, exploitation requires local access and low privileges but enables high-impact outcomes: denial of service, privilege escalation, information disclosure, data tampering, and code execution. The attack complexity is low and no user interaction is required, making this a significant risk for multi-user Linux environments with NVIDIA graphics deployments.

Defensive priority

high

Recommended defensive actions

Apply NVIDIA security update when available per vendor security bulletin
Restrict local access to systems running NVIDIA Display Driver for Linux
Audit and minimize accounts with local access privileges
Monitor for anomalous process behavior or unexpected driver crashes
Review system logs for indicators of privilege escalation attempts

Evidence notes

Vulnerability disclosed by NVIDIA PSIRT via NVD on 2026-05-26. CVSS vector confirms local attack surface with high impact on confidentiality, integrity, and availability. CWE-681 classification indicates integer conversion flaw leading to heap corruption.
