A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in the NVIDIA graphics driver kernel modules.
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. (CVE-2020-5973)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make all the necessary changes.
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.
