CVE-2021-1056
Published: 07 January 2021
NVIDIA GPU Display Driver for Linux, all versions, contains a vulnerability in the kernel mode layer (nvidia.ko) in which it does not completely honor operating system file system permissions to provide GPU device-level isolation, which may lead to denial of service or information disclosure.
From the Ubuntu security team
Xinyuan Lyu discovered that the NVIDIA GPU display driver for the Linux kernel did not properly restrict device-level GPU isolation. A local attacker could use this to cause a denial of service or possibly expose sensitive information.
