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)
