Ubuntu 20.04 LTS USN-6741-1: Moderate Linux Kernel Security Issues

Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-6741-1 April 19, 2024 linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, linux-bluefield, linux-gcp, linux-gcp-5.4, linux-gkeop, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-iot, linux-kvm, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4, linux-xilinx-zynqmp vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS (Available with Ubuntu Pro) 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-bluefield: Linux kernel for NVIDIA BlueField platforms - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-gkeop: Linux kernel for Google Container Engine (GKE) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-iot: Linux kernel for IoT platforms - linux-kvm: Linux kernel for cloud environments - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors - 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: Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allowan unauthenticated user to complete authentication without pairing credentials. A physically proximate attacker placed between two Bluetooth devices could use this to subsequently impersonate one of the paired devices. (CVE-2023-24023) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - JFS file system; - BPF subsystem; - Netfilter; (CVE-2023-52603, CVE-2023-52600, CVE-2024-26581, CVE-2024-26589) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.4.0-1035-iot 5.4.0-1035.36 linux-image-5.4.0-1042-xilinx-zynqmp 5.4.0-1042.46 linux-image-5.4.0-1070-ibm 5.4.0-1070.75 linux-image-5.4.0-1083-bluefield 5.4.0-1083.90 linux-image-5.4.0-1090-gkeop 5.4.0-1090.94 linux-image-5.4.0-1107-raspi 5.4.0-1107.119 linux-image-5.4.0-1111-kvm 5.4.0-1111.118 linux-image-5.4.0-1122-oracle 5.4.0-1122.131 linux-image-5.4.0-1123-aws 5.4.0-1123.133 linux-image-5.4.0-1127-gcp 5.4.0-1127.136 linux-image-5.4.0-1128-azure 5.4.0-1128.135 linux-image-5.4.0-177-generic 5.4.0-177.197 linux-image-5.4.0-177-generic-lpae 5.4.0-177.197 linux-image-5.4.0-177-lowlatency 5.4.0-177.197 linux-image-aws-lts-20.04 5.4.0.1123.120 linux-image-azure-lts-20.04 5.4.0.1128.122 linux-image-bluefield 5.4.0.1083.79 linux-image-gcp-lts-20.04 5.4.0.1127.129 linux-image-generic 5.4.0.177.175 linux-image-generic-lpae 5.4.0.177.175 linux-image-gkeop 5.4.0.1090.88 linux-image-gkeop-5.4 5.4.0.1090.88 linux-image-ibm-lts-20.04 5.4.0.1070.99 linux-image-kvm 5.4.0.1111.107 linux-image-lowlatency 5.4.0.177.175 linux-image-oem 5.4.0.177.175 linux-image-oem-osp1 5.4.0.177.175 linux-image-oracle-lts-20.04 5.4.0.1122.115 linux-image-raspi 5.4.0.1107.137 linux-image-raspi2 5.4.0.1107.137 linux-image-virtual 5.4.0.177.175 linux-image-xilinx-zynqmp 5.4.0.1042.42 Ubuntu 18.04 LTS (Available with Ubuntu Pro): linux-image-5.4.0-1070-ibm 5.4.0-1070.75~18.04.1 linux-image-5.4.0-1107-raspi 5.4.0-1107.119~18.04.1 linux-image-5.4.0-1122-oracle 5.4.0-1122.131~18.04.1 linux-image-5.4.0-1123-aws 5.4.0-1123.133~18.04.1 linux-image-5.4.0-1127-gcp 5.4.0-1127.136~18.04.1 linux-image-5.4.0-1128-azure 5.4.0-1128.135~18.04.1 linux-image-5.4.0-177-generic 5.4.0-177.197~18.04.1 linux-image-5.4.0-177-lowlatency 5.4.0-177.197~18.04.1 linux-image-aws 5.4.0.1123.133~18.04.1 linux-image-azure 5.4.0.1128.135~18.04.1 linux-image-gcp 5.4.0.1127.136~18.04.1 linux-image-generic-hwe-18.04 5.4.0.177.197~18.04.1 linux-image-ibm 5.4.0.1070.75~18.04.1 linux-image-lowlatency-hwe-18.04 5.4.0.177.197~18.04.1 linux-image-oem 5.4.0.177.197~18.04.1 linux-image-oem-osp1 5.4.0.177.197~18.04.1 linux-image-oracle 5.4.0.1122.131~18.04.1 linux-image-raspi-hwe-18.04 5.4.0.1107.119~18.04.1 linux-image-snapdragon-hwe-18.04 5.4.0.177.197~18.04.1 linux-image-virtual-hwe-18.04 5.4.0.177.197~18.04.1 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.
