Detailed vulnerability description
The vulnerability allows a local attacker to cause DoS condition or gain elevated privileges on the target system.
The weakness exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to insufficient validation of user-supplied input. A local attacker can provide a specially crafted value that is used as an index to an array, trigger NULL pointer dereference and cause denial of service or potentially escalate privileges.
Successful exploitation of the vulnerability may result in full access to the system.
