NVIDIA GPU Display Driver

CVE IDs	Description	Base Score	Vector
CVE‑2021‑1074	NVIDIA Windows GPU Display Driver installer contains a vulnerability where an attacker with local unprivileged system access may be able to replace an application resource with malicious files. This attack requires a user with system administration rights to execute the installer and requires the attacker to replace the files in a very short time window between file integrity validation and execution. Such an attack may lead to code execution, escalation of privileges, denial of service, and information disclosure.	7.3	AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
CVE‑2021‑1075	NVIDIA Windows GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape where the program dereferences a pointer that contains a location for memory that is no longer valid, which may lead to code execution, denial of service, or escalation of privileges. An attacker does not have any control over the information and may conduct only limited data modification.	7.3	AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:H
CVE‑2021‑1076	NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer (nvlddmkm.sys or nvidia.ko) where improper access control may lead to denial of service, information disclosure, or data corruption.

6.6

| AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H
CVE‑2021‑1077 | NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability where the software uses a reference count to manage a resource that is incorrectly updated, which may lead to denial of service. | 6.6 | AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H
CVE‑2021‑1078 |

NVIDIA Windows GPU Display Driver for Windows contains a vulnerability in the kernel driver (nvlddmkm.sys) where a NULL pointer dereference may lead to system crash.

| 5.5 | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

The NVIDIA risk assessment is based on an average of risk across a diverse set of installed systems and may not represent the true risk to your local installation. NVIDIA recommends consulting a security or IT professional to evaluate the risk to your specific configuration.

CVE‑2021‑1084	NVIDIA vGPU driver contains a vulnerability in the guest kernel mode driver and Virtual GPU Manager (vGPU plugin), in which an input length is not validated, which may lead to information disclosure, tampering of data, or denial of service.	7.8	AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2021‑1085	NVIDIA vGPU driver contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where there is the potential to write to a shared memory location and manipulate the data after the data has been validated, which may lead to denial of service, escalation of privileges, and information disclosure but attacker doesn’t have control over what information is obtained.	7.3	AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:H
CVE‑2021‑1086	NVIDIA vGPU driver contains a vulnerability in the Virtual GPU Manager (vGPU plugin) where it allows guests to control unauthorized resources, which may lead to integrity and confidentiality loss or information disclosure.	7.1	AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
CVE‑2021‑1087	NVIDIA vGPU driver contains a vulnerability in the Virtual GPU Manager (vGPU plugin), which could allow an attacker to retrieve information that could lead to a Address Space Layout Randomization (ASLR) bypass.	5.5	AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
