Description The issue is related to a buffer handling vulnerability in the kernel mode layer of the NVIDIA GPU Display Driver, specifically in the nvlddmkm.sys handler for control calls. This vulnerability may allow an attacker to cause data tampering or denial of service by reading or writing to a buffer using an index or pointer that references a memory location after the end of the buffer.
