Publication date

25 June 2020

Overview

Several security issues were fixed in the NVIDIA graphics driver kernel modules.

Packages

Details

USN-4404-1 fixed vulnerabilities in the NVIDIA graphics drivers.
This update provides the corresponding updates for the NVIDIA Linux
DKMS kernel modules.

Original advisory details:

Thomas E. Carroll discovered that the NVIDIA Cuda grpahics driver did not
properly perform access control when performing IPC. An attacker could use
this to cause a denial of service or possibly execute arbitrary code.
(CVE-2020-5963)

It was discovered that the UVM driver in the NVIDIA graphics driver
contained a race condition. A local attacker could use this to cause a
denial of service. (CVE-2020-5967)

It was discovered that the NVIDIA virtual GPU guest drivers contained
an unspecified vulnerability that could potentially lead to privileged
operation execution. An attacker could use this to cause a denial of
service. (

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

The problem can be corrected by updating your system to the following package versions:
