NONE Confidentiality impact
COMPLETE Integrity impact
COMPLETE Availability impact
COMPLETE Summary
All versions of NVIDIA Windows GPU Display Driver contain a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape where the size of an input buffer is not validated, leading to denial of service or potential escalation of privileges.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| NASL id | NVIDIA_WIN_CVE_2016_8826.NASL |
| description | The version of the NVIDIA GPU display driver installed on the remote Windows host is 340.x prior to 342.01 or 375.x prior to 376.33. It is, therefore, affected by multiple vulnerabilities : - A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper access controls. A local attacker can exploit this to access arbitrary memory and thereby gain elevated privileges. (CVE-2016-8821) - A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape IDs 0x600000E, 0x600000F, and 0x6000010 due to improper validation of user-supplied input that is used as an index to an internal array. A local attacker can exploit this to corrupt memory, resulting in a denial of service condition or an escalation of privileges. (CVE-2016-8822) - Multiple buffer overflow conditions exist in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper validation of an input buffer size. A local attacker can exploit these to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-8823, CVE-2016-8825) - A flaw exists in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape due to improper access controls. A local attacker can exploit this to write to restricted portions of the registry and thereby gain elevated privileges. (CVE-2016-8824) - A flaw exists in the nvlddmkm.sys driver that allows a local attacker to cause GPU interrupt saturation, resulting in a denial of service condition. (CVE-2016-8826) |
