CVE-2021-1057

Data exposure and service interruption via unauthorized allocation

Published Jan 8, 2021 · Updated Aug 3, 2024

Resource allocation flaw in NVIDIA Virtual GPU Manager 8.0 through 8.5 and 11.0 through 11.2 allows guest OS users to expose or alter data. The vGPU plugin grants a guest resources it is not authorized to allocate, but NVIDIA has not disclosed the affected request handler or resource type. A low-privileged guest can trigger the flaw locally without user interaction, causing data exposure, unauthorized modification, or host service interruption.
