========================================================================= 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: Ubuntu 20.04 LTS: linux-image-5.4.0-1017-aws 5.4.0-1017.17 linux-image-5.4.0-1018-gcp 5.4.0-1018.18 linux-image-5.4.0-1018-oracle 5.4.0-1018.18 linux-image-5.4.0-1019-azure 5.4.0-1019.19 linux-image-5.4.0-39-generic 5.4.0-39.43 linux-image-5.4.0-39-generic-lpae 5.4.0-39.43 linux-image-5.4.0-39-lowlatency 5.4.0-39.43 linux-image-aws 5.4.0.1017.18 linux-image-azure 5.4.0.1019.18 linux-image-gcp 5.4.0.1018.16 linux-image-generic 5.4.0.39.42 linux-image-generic-hwe-20.04 5.4.0.39.42 linux-image-generic-lpae 5.4.0.39.42 linux-image-generic-lpae-hwe-20.04 5.4.0.39.42 linux-image-gke 5.4.0.1018.16 linux-image-lowlatency 5.4.0.39.42 linux-image-lowlatency-hwe-20.04 5.4.0.39.42 linux-image-oem 5.4.0.39.42 linux-image-oem-osp1 5.4.0.39.42 linux-image-oracle 5.4.0.1018.16 linux-image-virtual 5.4.0.39.42 linux-image-virtual-hwe-20.04 5.4.0.39.42 Ubuntu 19.10: linux-image-5.3.0-1027-oracle 5.3.0-1027.29 linux-image-5.3.0-1028-aws 5.3.0-1028.30 linux-image-5.3.0-1029-gcp 5.3.0-1029.31 linux-image-5.3.0-61-generic 5.3.0-61.55 linux-image-5.3.0-61-generic-lpae 5.3.0-61.55 linux-image-5.3.0-61-lowlatency 5.3.0-61.55 linux-image-5.3.0-61-snapdragon 5.3.0-61.55 linux-image-aws 5.3.0.1028.38 linux-image-gcp 5.3.0.1029.39 linux-image-generic 5.3.0.61.51 linux-image-generic-lpae 5.3.0.61.51 linux-image-gke 5.3.0.1029.39 linux-image-lowlatency 5.3.0.61.51 linux-image-oracle 5.3.0.1027.42 linux-image-snapdragon 5.3.0.61.51 linux-image-virtual 5.3.0.61.51 Ubuntu 18.04 LTS: linux-image-4.15.0-1047-oracle 4.15.0-1047.51 linux-image-4.15.0-1076-aws 4.15.0-1076.80 linux-image-4.15.0-108-generic 4.15.0-108.109 linux-image-4.15.0-108-generic-lpae 4.15.0-108.109 linux-image-4.15.0-108-lowlatency 4.15.0-108.109 linux-image-4.15.0-1090-oem 4.15.0-1090.100 linux-image-5.0.0-1062-oem-osp1 5.0.0-1062.67 linux-image-5.3.0-1027-oracle 5.3.0-1027.29~18.04.1 linux-image-5.3.0-1028-aws 5.3.0-1028.30~18.04.1 linux-image-5.3.0-1029-gcp 5.3.0-1029.31~18.04.1 linux-image-5.3.0-1031-azure 5.3.0-1031.32~18.04.1 linux-image-5.3.0-61-generic 5.3.0-61.55~18.04.1 linux-image-5.3.0-61-generic-lpae 5.3.0-61.55~18.04.1 linux-image-5.3.0-61-lowlatency 5.3.0-61.55~18.04.1 linux-image-aws 5.3.0.1028.26 linux-image-aws-lts-18.04 4.15.0.1076.78 linux-image-azure 5.3.0.1031.27 linux-image-gcp 5.3.0.1029.23 linux-image-generic 4.15.0.108.96 linux-image-generic-hwe-18.04 5.3.0.61.114 linux-image-generic-lpae 4.15.0.108.96 linux-image-generic-lpae-hwe-18.04 5.3.0.61.114 linux-image-gkeop-5.3 5.3.0.61.114 linux-image-lowlatency 4.15.0.108.96 linux-image-lowlatency-hwe-18.04 5.3.0.61.114 linux-image-oem 4.15.0.1090.93 linux-image-oem-osp1 5.0.0.1062.60 linux-image-oracle 5.3.0.1027.24 linux-image-oracle-edge 5.3.0.1027.24 linux-image-oracle-lts-18.04 4.15.0.1047.56 linux-image-powerpc-e500mc 4.15.0.108.96 linux-image-powerpc-smp 4.15.0.108.96 linux-image-powerpc64-emb 4.15.0.108.96 linux-image-powerpc64-smp 4.15.0.108.96 linux-image-snapdragon-hwe-18.04 5.3.0.61.114 linux-image-virtual 4.15.0.108.96 linux-image-virtual-hwe-18.04 5.3.0.61.114 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.
