Ubuntu Security Notice 4404-2 - USN-4404-1 fixed vulnerabilities in the NVIDIA graphics drivers. This update provides the corresponding updates for the NVIDIA Linux DKMS kernel modules. Thomas E. Carroll discovered that the NVIDIA Cuda graphics 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. Various other issues were also addressed.

USN-4404-1 fixed vulnerabilities in the NVIDIA graphics drivers.
This update provides the corresponding updates for the NVIDIA Linux
DKMS kernel modules.
Original advisory 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)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:

After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
