NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the open-source kernel module DMA-BUF import path where an unprivileged local user could cause improper preservation of memory access permissions when importing a read-only buffer from another device's DMA-BUF exporter. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, denial of service, information disclosure, and data tampering.
