nvflsh64.sys
NVIDIA NVFlash GPU BIOS tool
nvflsh64.sys is the kernel driver for NVFlash, NVIDIA's GPU BIOS flashing utility. NVFlash is widely used by GPU enthusiasts and overclockers to read, back up, and modify the VBIOS on GeForce and RTX cards. The driver provides the direct PCI access that firmware flashing requires.
It is on the public LOLDrivers list for that low-level access surface. If you have used NVFlash to back up or modify your GPU BIOS, the driver is expected. Use the latest version from NVIDIA or TechPowerUp.
nvflsh64.sys is listed as a known-vulnerable driver on the public LOLDrivers project. One distinct binary hash matching this filename is on record.
Status data comes from the public LOLDrivers project, a community-curated registry of drivers known to be vulnerable or malicious. The snapshot Vera uses was refreshed July 10, 2026. CVE links go to the NIST National Vulnerability Database.
