========================================================================== Ubuntu Security Notice USN-4689-2 January 11, 2021
linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-4.15, linux-azure-5.4, linux-gcp, linux-gcp-5.4, linux-hwe-5.4, linux-hwe-5.8, linux-oem-5.6, linux-oracle, linux-oracle-5.4 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
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-hwe-5.8: Linux hardware enablement (HWE) kernel - linux-oem-5.6: Linux kernel for OEM systems - linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems - linux-azure-4.15: Linux kernel for Microsoft Azure Cloud systems - linux-azure-5.4: Linux kernel for Microsoft Azure cloud systems - linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-5.4: Linux hardware enablement (HWE) kernel - linux-oracle-5.4: Linux kernel for Oracle Cloud systems
Details:
USN-4689-1 fixed vulnerabilities in the NVIDIA graphics drivers. This update provides the corresponding updates for the NVIDIA Linux DKMS kernel modules.
Original advisory details:
It was discovered that the NVIDIA GPU display driver for the Linux kernel contained a vulnerability that allowed user-mode clients to access legacy privileged APIs. A local attacker could use this to cause a denial of service or escalate privileges. (CVE-2021-1052)
It was discovered that the NVIDIA GPU display driver for the Linux kernel did not properly validate a pointer received from userspace in some situations. A local attacker could use this to cause a denial of service. (CVE-2021-1053)
Xinyuan Lyu discovered that the NVIDIA GPU display driver for the Linux kernel did not properly restrict device-level GPU isolation. A local attacker could use this to cause a denial of service or possibly expose sensitive information. (CVE-2021-1056)
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.
