=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 19.10
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in the NVIDIA graphics driver
kernel modules.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-aws-5.3: Linux kernel for Amazon Web Services (AWS) systems
- linux-azure-5.3: Linux kernel for Microsoft Azure Cloud systems
- linux-gcp-5.3: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe: Linux hardware enablement (HWE) kernel
- linux-oem: Linux kernel for OEM systems
- linux-oem-osp1: Linux kernel for OEM systems
- linux-oracle-5.3: Linux kernel for Oracle Cloud systems

Details:

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)

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.
