Doc Text:
A flaw was found in the NVIDIA GPU display driver open-source kernel module. An unprivileged local user can trigger this vulnerability when importing a read-only buffer from another device via the Direct Memory Access Buffer (DMA-BUF) sharing framework, leading to improper preservation of memory access permissions. Successful exploitation can allow a local attacker to achieve privilege escalation, execute arbitrary code, cause a denial of service, or tamper with system data.

Description OSIDB Bzimport 2026-09-30 16:32:06 UTC 
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.
