Technical details
A Time-of-Check Time-of-Use (TOCTOU) race condition vulnerability (CWE-367) exists in the NVIDIA Display Driver for Windows. An attacker with local user access can exploit this race condition during the driver's validation of a resource, modifying the resource after it has been checked but before it is used. Successful exploitation requires high attack complexity due to the timing requirements but can result in a scope cross (S:C), allowing for local privilege escalation, arbitrary code execution, information disclosure, or denial of service. Users are advised to refer to NVIDIA advisory 5821 for specific driver version updates and patches.
