January 11, 2021

nvidia-graphics-drivers-390, nvidia-graphics-drivers-450,
nvidia-graphics-drivers-460 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in NVIDIA graphics drivers.

Software Description:
- nvidia-graphics-drivers-390: NVIDIA binary X.Org driver
- nvidia-graphics-drivers-450: NVIDIA binary X.Org driver
- nvidia-graphics-drivers-460: NVIDIA binary X.Org driver

Details:

It was discovered that the NVIDIA GPU display driver for the Linux kernel
contained a vulnerability that allowed user-mode clients to access legacy
privileged APIs. A local attacker could use this to cause a denial of
service or escalate privileges. (CVE-2021-1052)

It was discovered that the NVIDIA GPU display driver for the Linux kernel
did not properly validate a pointer received from userspace in some
situations. A local attacker could use this to cause a denial of service.
(CVE-2021-1053)

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. (CVE-2021-1056)
