Details

This section provides a summary of potential vulnerabilities that this security update addresses and their impact. Descriptions use CWE™, and base scores and vectors use CVSS v3.1 standards.

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handler for DxgkDdiEscape where the program dereferences a pointer that contains a location for memory that is no longer valid, which may lead to code execution, denial of service, or escalation of privileges.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.

NVIDIA vGPU Software

CVE‑2021‑1081 NVIDIA vGPU software 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‑2021‑1082 NVIDIA vGPU software contains a vulnerability in the 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‑2021‑1083 NVIDIA vGPU software 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‑2021‑1084 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
