CVE-2026-24191

Vulnerability

CVE-2026-24191 is a time-of-check time-of-use (TOCTOU) vulnerability in the NVIDIA Display Driver for Windows. The exact affected driver versions are not specified in the available references [1]. The vulnerability arises when the driver performs a check on a resource and then uses that resource without proper synchronization, allowing a race condition to be exploited.

Exploitation

An attacker with local access to the system could exploit this TOCTOU issue by manipulating the resource between the time it is checked and the time it is used. The attacker would need to win a race window, which may require precise timing or repeated attempts. No authentication or user interaction beyond local access is specified in the available references [1].

Impact

Successful exploitation could lead to denial of service, escalation of privileges, information disclosure, data tampering, or arbitrary code execution. The exact privilege level or scope of compromise is not detailed in the available references [1].

Mitigation

No mitigation or fixed version has been disclosed in the available references [1]. Users should monitor NVIDIA's security advisories for driver updates and apply them as soon as they become available.
