For the NVIDIA Quadro, NVS, and GeForce products, NVIDIA Windows GPU Display Driver R340 before 342.00 and R375 before 375.63 contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x70001b2 where the size of an input buffer is not validated, leading to denial of service or potential escalation of privileges.

Security readout for executives and security teams

This is a legacy NVIDIA Windows display driver flaw affecting Quadro, NVS, and GeForce systems on specific old R340 and R375 driver branches. A bad input buffer size check in the kernel-mode driver can crash the system or potentially let a local attacker gain higher privileges. Exposure is most likely on older Windows endpoints, workstations, or systems with NVIDIA Quadro, NVS, or GeForce GPUs running R340 before 342.00 or R375 before 375.63. Address during legacy Windows driver hygiene work, with higher priority for shared systems, lab machines, or endpoints where many users can log in. The main business risk is local disruption or privilege escalation from outdated GPU drivers, not confirmed remote exploitation. Mitigation focus: Inventory Windows systems with NVIDIA Quadro, NVS, or GeForce drivers.; Upgrade R340 systems to 342.00 or later, per vendor guidance.; Upgrade R375 systems to 375.63 or later, per vendor guidance..
