NVIDIA GPU Display Driver

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.
CVE ID Description Base Score Vector
CVE‑2021‑1089 NVIDIA GPU Display Driver for Windows contains a vulnerability in nvidia-smi where an uncontrolled DLL loading path may lead to arbitrary code execution, denial of service, information disclosure, and data tampering. 7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2021‑1090 NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for control calls where the software reads or writes to a buffer by using an index or pointer that references a memory location after the end of the buffer, which may lead to data tampering or denial of service. 7.1 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
CVE‑2021‑1091 NVIDIA GPU Display driver for Windows contains a vulnerability where an unprivileged user can create a file hard link that causes the driver to overwrite a file that requires elevated privilege to modify, which could lead to data loss or denial of service. 7.1 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
CVE‑2021‑1092 NVIDIA GPU Display Driver for Windows contains a vulnerability in the NVIDIA Control Panel application where it is susceptible to a Windows file system symbolic link attack where an unprivileged attacker can cause the applications to overwrite privileged files, resulting in potential denial of service or data loss. 7.1 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
CVE‑2021‑1093 NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in firmware where the driver contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary, and may lead to denial of service or system crash. 6.2 AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CVE‑2021‑1094 NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape where an out of bounds array access may lead to denial of service or information disclosure. 6.1 AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H
CVE‑2021‑1095 NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handlers for all control calls with embedded parameters where dereferencing an untrusted pointer may lead to denial of service. 5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
CVE‑2021‑1096 NVIDIA Windows GPU Display Driver for Windows contains a vulnerability in the NVIDIA kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape where dereferencing a NULL pointer may lead to a system crash. 5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

NVIDIA vGPU Software

NVIDIA vGPU Softwar
CVE ID Description Base Score Vector
CVE‑2021‑1097 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it improperly validates the length field in a request from a guest. This flaw allows a malicious guest to send a length field that is inconsistent with the actual length of the input, which may lead to information disclosure, data tampering, or denial of service. 7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2021‑1098 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it doesn't release some resources during driver unload requests from guests. This flaw allows a malicious guest to perform operations by reusing those resources, which may lead to information disclosure, data tampering, or denial of service. 7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2021‑1099 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin) that could allow an attacker to cause stack-based buffer overflow and put a customized ROP gadget on the stack. Such an attack may lead to information disclosure, data tampering, or denial of service. 7.0 AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2021‑1100 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager kernel mode driver (nvidia.ko), in which a pointer to a user-space buffer is not validated before it is dereferenced, which may lead to denial of service. 6.2 AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CVE‑2021‑1101 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it can dereference a NULL pointer, which may lead to denial of service. 5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
CVE‑2021‑1102 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it can lead to floating point exceptions, which may lead to denial of service. 5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
CVE‑2021‑1103 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it can dereference a NULL pointer, which may lead to denial of service. 4.4 AV:L/AC:L/PR:H/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.
