Detailsinfo

A vulnerability was found in NVIDIA GPU Driver (Hardware Driver Software) (unknown version) and classified as critical. Affected by this issue is the function DxgDdiEscape in the library nvlddmkm.sys of the component Kernel Mode Layer. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. CVE summarizes:

All versions of NVIDIA Windows GPU Display contain a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape where a pointer passed from a user to the driver is used without validation, leading to denial of service or potential escalation of privileges.
