  - NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where a
    user could cause an out-of-bounds read leading to kernel information disclosure. A successful exploit of
    this vulnerability might lead to code execution, denial of service, escalation of privileges, information
    disclosure, and data tampering. (CVE-2026-47512)
