The new security patches address three vulnerabilities affecting Ubuntu 20.04 LTS, Ubuntu 19.10 and Ubuntu 18.04 LTS. These include a vulnerability (CVE-2020-5963) discovered by Thomas E. Carroll in the NVIDIA Cuda grpahics driver, which could allow an attacker to cause a denial of service or possibly execute arbitrary code. The other two security issues were an unspecified vulnerability (CVE-2020-5973) discovered in the NVIDIA virtual GPU guest drivers that could potentially lead to privileged operation execution and a race condition (CVE-2020-5967) discovered in the UVM driver in the NVIDIA graphics driver. Both these vulnerabilities could allow a local attacker to cause a denial of service.
