Three security vulnerabilities are affecting the NVIDIA graphics drivers in Ubuntu 20.10 (Groovy Gorilla), Ubuntu 20.04 LTS (Focal Fossa), and Ubuntu 18.04 LTS (Bionic Beaver) operating system series that could allow local attackers to cause a denial of service or escalate privileges. All users are urged to update their NVIDIA graphics drivers as soon as possible to the new versions available in the stable software repositories. The 460.32.03, 450.102.04, and 390.141 versions are available for Ubuntu 20.10, Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS, and are based on the latest NVIDIA display driver upstream release that also includes various other bug fixes and improvements.
