 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)
