========================================================================== Ubuntu Security Notice USN-6027-1 April 19, 2023 linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, linux-gcp, linux-gcp-5.4, linux-gke, linux-gkeop, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-kvm, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - 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-gke: Linux kernel for Google Container Engine (GKE) systems - linux-gkeop: Linux kernel for Google Container Engine (GKE) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-kvm: Linux kernel for cloud environments - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) 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-ibm-5.4: Linux kernel for IBM cloud systems - linux-oracle-5.4: Linux kernel for Oracle Cloud systems - linux-raspi-5.4: Linux kernel for Raspberry Pi systems 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) Jiasheng Jiang discovered that the HSA Linux kernel driver for AMD Radeon GPU devices did not properly validate memory allocation in certain situations, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3108) 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) Haowei Yan discovered that a race condition existed in the Layer 2 Tunneling Protocol (L2TP) implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-4129) 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 20.04 LTS: linux-image-5.4.0-1047-ibm 5.4.0-1047.52 linux-image-5.4.0-1067-gkeop 5.4.0-1067.71 linux-image-5.4.0-1083-raspi 5.4.0-1083.94 linux-image-5.4.0-1089-kvm 5.4.0-1089.95 linux-image-5.4.0-1097-gke 5.4.0-1097.104 linux-image-5.4.0-1099-oracle 5.4.0-1099.108 linux-image-5.4.0-1100-aws 5.4.0-1100.108 linux-image-5.4.0-1103-gcp 5.4.0-1103.112 linux-image-5.4.0-1106-azure 5.4.0-1106.112 linux-image-5.4.0-147-generic 5.4.0-147.164 linux-image-5.4.0-147-generic-lpae 5.4.0-147.164 linux-image-5.4.0-147-lowlatency 5.4.0-147.164 linux-image-aws-lts-20.04 5.4.0.1100.97 linux-image-azure-lts-20.04 5.4.0.1106.99 linux-image-gcp-lts-20.04 5.4.0.1103.105 linux-image-generic 5.4.0.147.145 linux-image-generic-lpae 5.4.0.147.145 linux-image-gke 5.4.0.1097.102 linux-image-gke-5.4 5.4.0.1097.102 linux-image-gkeop 5.4.0.1067.65 linux-image-gkeop-5.4 5.4.0.1067.65 linux-image-ibm 5.4.0.1047.73 linux-image-ibm-lts-20.04 5.4.0.1047.73 linux-image-kvm 5.4.0.1089.83 linux-image-lowlatency 5.4.0.147.145 linux-image-oem 5.4.0.147.145 linux-image-oem-osp1 5.4.0.147.145 linux-image-oracle-lts-20.04 5.4.0.1099.92 linux-image-raspi 5.4.0.1083.113 linux-image-raspi2 5.4.0.1083.113 linux-image-virtual 5.4.0.147.145 Ubuntu 18.04 LTS: linux-image-5.4.0-1047-ibm 5.4.0-1047.52~18.04.1 linux-image-5.4.0-1083-raspi 5.4.0-1083.94~18.04.1 linux-image-5.4.0-1099-oracle 5.4.0-1099.108~18.04.1 linux-image-5.4.0-1100-aws 5.4.0-1100.108~18.04.1 linux-image-5.4.0-1103-gcp 5.4.0-1103.112~18.04.1 linux-image-5.4.0-1106-azure 5.4.0-1106.112~18.04.1 linux-image-5.4.0-147-generic 5.4.0-147.164~18.04.1 linux-image-5.4.0-147-generic-lpae 5.4.0-147.164~18.04.1 linux-image-5.4.0-147-lowlatency 5.4.0-147.164~18.04.1 linux-image-aws 5.4.0.1100.78 linux-image-azure 5.4.0.1106.79 linux-image-gcp 5.4.0.1103.79 linux-image-generic-hwe-18.04 5.4.0.147.164~18.04.118 linux-image-generic-lpae-hwe-18.04 5.4.0.147.164~18.04.118 linux-image-ibm 5.4.0.1047.58 linux-image-lowlatency-hwe-18.04 5.4.0.147.164~18.04.118 linux-image-oem 5.4.0.147.164~18.04.118 linux-image-oem-osp1 5.4.0.147.164~18.04.118 linux-image-oracle 5.4.0.1099.108~18.04.71 linux-image-raspi-hwe-18.04 5.4.0.1083.80 linux-image-snapdragon-hwe-18.04 5.4.0.147.164~18.04.118 linux-image-virtual-hwe-18.04 5.4.0.147.164~18.04.118 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.
