========================================================================== Ubuntu Security Notice USN-4404-2 June 25, 2020
linux kernel vulnerabilities ==========================================================================
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)
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.
