NVIDIA GPU Driver R340 any version

The Escape interface in the Kernel Mode Driver layer in the NVIDIA GPU graphics driver R340 before 341.95 and R352 before 354.74 on Windows improperly allows access to restricted functionality, which allows local users to gain privileges via unspecified vectors.

The NVIDIA Display Driver R304 before 309.08, R340 before 341.44, R343 before 345.20, and R346 before 347.52 does not properly validate local client impersonation levels when performing a "kernel administrator check," which allows local users to gain administrator privileges via unspecified API calls.
