NVIDIA GPU Display Driver

CVE ID Description Base Score Vector
CVE‑2021‑1115 NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for private IOCTLs, where an attacker with local unprivileged system access may cause a NULL pointer dereference, which may lead to denial of service in a component beyond the vulnerable component. 6.5 AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H
CVE‑2021‑1116 NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys), where a NULL pointer dereference in the kernel, created within user mode code, may lead to a denial of service in the form of a system crash. 5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
CVE‑2021‑1117 NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape, where an attacker through specific configuration and with local unprivileged system access may cause improper input validation, which may lead to denial of service. 4.7 AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H

NVIDIA vGPU Software

CVE ID Description Base Score Vector
CVE‑2021‑1118 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where there is the potential to execute privileged operations by the guest OS, which may lead to information disclosure, data tampering, escalation of privileges, and denial of service. 7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2021‑1119 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it can double-free a pointer, which may lead to denial of service. This flaw may result in a write-what-where condition, allowing an attacker to execute arbitrary code impacting integrity and availability. 7.1 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
CVE‑2021‑1120 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where a string provided by the guest OS may not be properly null terminated. The guest OS or attacker has no ability to push content to the plugin through this vulnerability, which may lead to information disclosure, data tampering, unauthorized code execution, and denial of service. 7.0 AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2021‑1121 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager kernel driver, where a vGPU can cause resource starvation among other vGPUs hosted on the same GPU, 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‑2021‑1122 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‑2021‑1123 NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where it can deadlock, 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

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.
