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.
