CVE-2026-24194

Vulnerability

CVE-2026-24194 is a vulnerability in the NVIDIA Display Driver for Linux, specifically in a kernel mode layer handler. The flaw involves improper permission handling that can be triggered by a local user. The affected driver versions are not explicitly listed in the available reference [1], but the issue resides in the kernel-mode component of the NVIDIA graphics driver.

Exploitation

An attacker must have local user access to the system. No additional authentication or special privileges are required beyond a standard user account. The exploitation sequence involves invoking the vulnerable kernel mode handler with crafted inputs that bypass permission checks, leading to unauthorized operations within the kernel context.

Impact

Successful exploitation can result in denial of service (system crash or hang), escalation of privileges to root or kernel level, disclosure of sensitive information, tampering with system data, and arbitrary code execution in kernel mode. The attacker gains full control over the affected system.

Mitigation

As of the publication date (2026-05-26), no official fix or patched driver version has been disclosed in the available reference [1]. Users should monitor NVIDIA's security bulletin for driver updates. Until a patch is released, limiting local user access and applying the principle of least privilege may reduce risk.
