    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-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.
