NVIDIA Linux GPU Display Driver, all versions, contains a vulnerability in the UVM driver, in which a race condition may lead to a denial of service.

The NVIDIA GPU display driver software on the remote host is missing a security update. It is, therefore, affected by multiple vulnerabilities:

  - A code execution vulnerability exists in the Inter Process Communication APIs due to improper access     control. An authenticated, local attacker can exploit this issue to cause a denial of service condition,     execute code or disclose potentially sensitive information. (CVE‑2020‑5963)   
  - A denial of service vulnerability exists in the UVM driver due to a race condition. A local authenticated     attacker could exploit this issued to cause a denial of service condition. (CVE‑2020‑5967)

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4404-2 advisory.

    USN-4404-1 fixed vulnerabilities in the NVIDIA graphics drivers. This update provides the corresponding     updates for the NVIDIA Linux DKMS kernel modules.



Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4404-1 advisory.

    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)
