NVIDIA GPU Display Driver

CVE IDs	Description	Base Score	Vector
CVE‑2020‑5979	NVIDIA Display Driver contains a vulnerability in the Control Panel component in which a user is presented with a dialog box for input by a high-privilege process, which may lead to escalation of privileges.	7.8	AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

CVE‑2020‑5980

| NVIDIA Windows GPU Display Driver contains a vulnerability in multiple components in which a securely loaded system DLL will load its dependencies in an insecure fashion, which may lead to code execution or denial of service. | 7.8 | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2020‑5981 | NVIDIA Windows GPU Display Driver contains a vulnerability in the DirectX11 user mode driver (nvwgf2um/x.dll), in which a specially crafted shader can cause an out of bounds access, which may lead to denial of service or code execution. | 7.8 | AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H
CVE‑2020‑5982 | NVIDIA Windows GPU Display Driver contains a vulnerability in the kernel mode layer (nvlddmkm.sys) scheduler, in which the software does not properly limit the number or frequency of interactions that it has with an actor, such as the number of incoming requests, 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

NVIDIA vGPU Software

CVE IDs	Description	Base Score	Vector
CVE‑2020‑5983	NVIDIA Virtual GPU Manager contains a vulnerability in the vGPU plugin and the host driver kernel module, in which the potential exists to write to a memory location that is outside the intended boundary of the frame buffer memory allocated to guest operating systems, which may lead to denial of service or information disclosure.	8.8	AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
CVE‑2020‑5984	NVIDIA Virtual GPU Manager contains a vulnerability in the vGPU plugin in which it may have the use-after-free vulnerability while freeing some resources, which may lead to denial of service, code execution, and information disclosure.	7.8	AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2020‑5985	NVIDIA Virtual GPU Manager contains a vulnerability in the vGPU plugin, in which an input data length is not validated, which may lead to tampering or denial of service.	7.8	AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2020‑5986	NVIDIA Virtual GPU Manager contains a vulnerability in the vGPU plugin, in which an input data size is not validated, which may lead to tampering or denial of service.	7.8	AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2020‑5987	NVIDIA Virtual GPU Manager contains a vulnerability in the vGPU plugin in which guest-supplied parameters remain writable by the guest after the plugin has validated them, which may lead to the guest being able to pass invalid parameters to plugin handlers, which may lead to denial of service or escalation of privileges.	7.3	AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:H
CVE‑2020‑5988	NVIDIA Virtual GPU Manager contains a vulnerability in the vGPU plugin, in which allocated memory can be freed twice, which may lead to information disclosure or denial of service.	7.0	AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
CVE‑2020‑5989	NVIDIA Virtual GPU Manager contains a vulnerability in the vGPU plugin, in which 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
