========================================================================== Ubuntu Security Notice USN-6029-1 April 19, 2023 linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-dell300x, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-raspi2 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS - Ubuntu 16.04 ESM - Ubuntu 14.04 ESM 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-4.15: Linux kernel for Microsoft Azure Cloud systems - linux-dell300x: Linux kernel for Dell 300x platforms - linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems - linux-kvm: Linux kernel for cloud environments - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi2: Linux kernel for Raspberry Pi systems - linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe: Linux hardware enablement (HWE) kernel Details: It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1281) It was discovered that the infrared transceiver USB driver did not properly handle USB control messages. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (memory exhaustion). (CVE-2022-3903) It was discovered that the Human Interface Device (HID) support driver in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1073) It was discovered that a memory leak existed in the SCTP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2023-1074) Lianhui Tang discovered that the MPLS implementation in the Linux kernel did not properly handle certain sysctl allocation failure conditions, leading to a double-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2023-26545) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1063-dell300x 4.15.0-1063.68 linux-image-4.15.0-1117-oracle 4.15.0-1117.128 linux-image-4.15.0-1130-raspi2 4.15.0-1130.138 linux-image-4.15.0-1138-kvm 4.15.0-1138.143 linux-image-4.15.0-1148-gcp 4.15.0-1148.164 linux-image-4.15.0-1154-aws 4.15.0-1154.167 linux-image-4.15.0-1163-azure 4.15.0-1163.178 linux-image-4.15.0-209-generic 4.15.0-209.220 linux-image-4.15.0-209-generic-lpae 4.15.0-209.220 linux-image-4.15.0-209-lowlatency 4.15.0-209.220 linux-image-aws-lts-18.04 4.15.0.1154.152 linux-image-azure-lts-18.04 4.15.0.1163.131 linux-image-dell300x 4.15.0.1063.62 linux-image-gcp-lts-18.04 4.15.0.1148.162 linux-image-generic 4.15.0.209.192 linux-image-generic-lpae 4.15.0.209.192 linux-image-kvm 4.15.0.1138.129 linux-image-lowlatency 4.15.0.209.192 linux-image-oracle-lts-18.04 4.15.0.1117.122 linux-image-raspi2 4.15.0.1130.125 linux-image-virtual 4.15.0.209.192 Ubuntu 16.04 ESM: linux-image-4.15.0-1117-oracle 4.15.0-1117.128~16.04.1 linux-image-4.15.0-1148-gcp 4.15.0-1148.164~16.04.1 linux-image-4.15.0-1154-aws 4.15.0-1154.167~16.04.1 linux-image-4.15.0-1163-azure 4.15.0-1163.178~16.04.1 linux-image-4.15.0-209-generic 4.15.0-209.220~16.04.1 linux-image-4.15.0-209-lowlatency 4.15.0-209.220~16.04.1 linux-image-aws-hwe 4.15.0.1154.137 linux-image-azure 4.15.0.1163.147 linux-image-gcp 4.15.0.1148.138 linux-image-generic-hwe-16.04 4.15.0.209.194 linux-image-gke 4.15.0.1148.138 linux-image-lowlatency-hwe-16.04 4.15.0.209.194 linux-image-oem 4.15.0.209.194 linux-image-oracle 4.15.0.1117.98 linux-image-virtual-hwe-16.04 4.15.0.209.194 Ubuntu 14.04 ESM: linux-image-4.15.0-1163-azure 4.15.0-1163.178~14.04.1 linux-image-azure 4.15.0.1163.129 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.
