Detailsinfo

A vulnerability, which was classified as very critical, has been found in NVIDIA GeForce, RTX, Quadro, NVS, Tesla and Virtual GPU Manager. This issue affects an unknown code of the component Kernel Mode Layer. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer where an attacker could cause an incorrect buffer size calculation. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.

The identification of this vulnerability is CVE-2026-47578 since 05/19/2026. The exploitation is known to be easy. Attacking locally is a requirement.
