========================================================================= Ubuntu Security Notice USN-7028-1 September 23, 2024 linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS - Ubuntu 16.04 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-4.15: Linux kernel for Microsoft Azure Cloud systems - 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-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 JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service (system crash). 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: - GPU drivers; - Greybus drivers; - Modular ISDN driver; - Multiple devices driver; - Network drivers; - SCSI drivers; - VFIO drivers; - F2FS file system; - GFS2 file system; - JFS file system; - NILFS2 file system; - Kernel debugger infrastructure; - Bluetooth subsystem; - IPv4 networking; - L2TP protocol; - Netfilter; - RxRPC session sockets; (CVE-2024-42154, CVE-2023-52527, CVE-2024-26733, CVE-2024-42160, CVE-2021-47188, CVE-2024-38570, CVE-2024-26851, CVE-2024-26984, CVE-2024-26677, CVE-2024-39480, CVE-2024-27398, CVE-2022-48791, CVE-2024-42224, CVE-2024-38583, CVE-2024-40902, CVE-2023-52809, CVE-2024-39495, CVE-2024-26651, CVE-2024-26880, CVE-2024-42228, CVE-2024-27437, CVE-2022-48863) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS linux-image-4.15.0-1135-oracle 4.15.0-1135.146 Available with Ubuntu Pro linux-image-4.15.0-1156-kvm 4.15.0-1156.161 Available with Ubuntu Pro linux-image-4.15.0-1166-gcp 4.15.0-1166.183 Available with Ubuntu Pro linux-image-4.15.0-1173-aws 4.15.0-1173.186 Available with Ubuntu Pro linux-image-4.15.0-1181-azure 4.15.0-1181.196 Available with Ubuntu Pro linux-image-4.15.0-229-generic 4.15.0-229.241 Available with Ubuntu Pro linux-image-4.15.0-229-lowlatency 4.15.0-229.241 Available with Ubuntu Pro linux-image-aws-lts-18.04 4.15.0.1173.171 Available with Ubuntu Pro linux-image-azure-lts-18.04 4.15.0.1181.149 Available with Ubuntu Pro linux-image-gcp-lts-18.04 4.15.0.1166.179 Available with Ubuntu Pro linux-image-generic 4.15.0.229.213 Available with Ubuntu Pro linux-image-kvm 4.15.0.1156.147 Available with Ubuntu Pro linux-image-lowlatency 4.15.0.229.213 Available with Ubuntu Pro linux-image-oracle-lts-18.04 4.15.0.1135.140 Available with Ubuntu Pro linux-image-virtual 4.15.0.229.213 Available with Ubuntu Pro Ubuntu 16.04 LTS linux-image-4.15.0-1135-oracle 4.15.0-1135.146~16.04.1 Available with Ubuntu Pro linux-image-4.15.0-1166-gcp 4.15.0-1166.183~16.04.1 Available with Ubuntu Pro linux-image-4.15.0-1173-aws 4.15.0-1173.186~16.04.1 Available with Ubuntu Pro linux-image-4.15.0-1181-azure 4.15.0-1181.196~16.04.1 Available with Ubuntu Pro linux-image-4.15.0-229-generic 4.15.0-229.241~16.04.1 Available with Ubuntu Pro linux-image-4.15.0-229-lowlatency 4.15.0-229.241~16.04.1 Available with Ubuntu Pro linux-image-aws-hwe 4.15.0.1173.186~16.04.1 Available with Ubuntu Pro linux-image-azure 4.15.0.1181.196~16.04.1 Available with Ubuntu Pro linux-image-gcp 4.15.0.1166.183~16.04.1 Available with Ubuntu Pro linux-image-generic-hwe-16.04 4.15.0.229.241~16.04.1 Available with Ubuntu Pro linux-image-gke 4.15.0.1166.183~16.04.1 Available with Ubuntu Pro linux-image-lowlatency-hwe-16.04 4.15.0.229.241~16.04.1 Available with Ubuntu Pro linux-image-oem 4.15.0.229.241~16.04.1 Available with Ubuntu Pro linux-image-oracle 4.15.0.1135.146~16.04.1 Available with Ubuntu Pro linux-image-virtual-hwe-16.04 4.15.0.229.241~16.04.1 Available with Ubuntu Pro 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.
