========================================================================== Ubuntu Security Notice USN-6686-1 March 08, 2024 linux, linux-azure, linux-azure-5.15, linux-azure-fde, linux-azure-fde-5.15, linux-gcp, linux-gcp-5.15, linux-gke, linux-gkeop, linux-gkeop-5.15, linux-hwe-5.15, linux-ibm, linux-ibm-5.15, linux-lowlatency-hwe-5.15, linux-nvidia vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-azure-fde: Linux kernel for Microsoft Azure CVM 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-nvidia: Linux kernel for NVIDIA systems - linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems - linux-azure-fde-5.15: Linux kernel for Microsoft Azure CVM cloud systems - linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems - linux-gkeop-5.15: Linux kernel for Google Container Engine (GKE) systems - linux-hwe-5.15: Linux hardware enablement (HWE) kernel - linux-ibm-5.15: Linux kernel for IBM cloud systems - linux-lowlatency-hwe-5.15: Linux low latency kernel Details: It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the Linux kernel did not properly handle certain error conditions during device registration. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-22995) It was discovered that a race condition existed in the Cypress touchscreen driver in the Linux kernel during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4134) 黄思聪 discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46343) It was discovered that the io_uring subsystem in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46862) It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to 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-2023-51779) It was discovered that a race condition existed in the Rose X.25 protocol implementation in the Linux kernel, leading to 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-2023-51782) Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker could use this to expose sensitive information (kernel memory). (CVE-2023-6121) It was discovered that the VirtIO subsystem in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to possibly expose sensitive information (kernel memory). (CVE-2024-0340) Dan Carpenter discovered that the netfilter subsystem in the Linux kernel did not store data in properly sized memory locations. A local user could use this to cause a denial of service (system crash). (CVE-2024-0607) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.15.0-100-generic 5.15.0-100.110 linux-image-5.15.0-100-generic-64k 5.15.0-100.110 linux-image-5.15.0-100-generic-lpae 5.15.0-100.110 linux-image-5.15.0-1038-gkeop 5.15.0-1038.44 linux-image-5.15.0-1046-nvidia 5.15.0-1046.46 linux-image-5.15.0-1046-nvidia-lowlatency 5.15.0-1046.46 linux-image-5.15.0-1048-ibm 5.15.0-1048.51 linux-image-5.15.0-1052-gke 5.15.0-1052.57 linux-image-5.15.0-1053-gcp 5.15.0-1053.61 linux-image-5.15.0-1058-azure 5.15.0-1058.66 linux-image-5.15.0-1058-azure-fde 5.15.0-1058.66.1 linux-image-azure-fde-lts-22.04 5.15.0.1058.66.36 linux-image-azure-lts-22.04 5.15.0.1058.54 linux-image-gcp-lts-22.04 5.15.0.1053.49 linux-image-generic 5.15.0.100.97 linux-image-generic-64k 5.15.0.100.97 linux-image-generic-lpae 5.15.0.100.97 linux-image-gke 5.15.0.1052.51 linux-image-gke-5.15 5.15.0.1052.51 linux-image-gkeop 5.15.0.1038.37 linux-image-gkeop-5.15 5.15.0.1038.37 linux-image-ibm 5.15.0.1048.44 linux-image-nvidia 5.15.0.1046.46 linux-image-nvidia-lowlatency 5.15.0.1046.46 linux-image-virtual 5.15.0.100.97 Ubuntu 20.04 LTS: linux-image-5.15.0-100-generic 5.15.0-100.110~20.04.1 linux-image-5.15.0-100-generic-64k 5.15.0-100.110~20.04.1 linux-image-5.15.0-100-generic-lpae 5.15.0-100.110~20.04.1 linux-image-5.15.0-100-lowlatency 5.15.0-100.110~20.04.1 linux-image-5.15.0-100-lowlatency-64k 5.15.0-100.110~20.04.1 linux-image-5.15.0-1038-gkeop 5.15.0-1038.44~20.04.1 linux-image-5.15.0-1048-ibm 5.15.0-1048.51~20.04.1 linux-image-5.15.0-1053-gcp 5.15.0-1053.61~20.04.1 linux-image-5.15.0-1058-azure 5.15.0-1058.66~20.04.2 linux-image-5.15.0-1058-azure-fde 5.15.0-1058.66~20.04.2.1 linux-image-azure 5.15.0.1058.66~20.04.48 linux-image-azure-cvm 5.15.0.1058.66~20.04.48 linux-image-azure-fde 5.15.0.1058.66~20.04.1.36 linux-image-gcp 5.15.0.1053.61~20.04.1 linux-image-generic-64k-hwe-20.04 5.15.0.100.110~20.04.52 linux-image-generic-hwe-20.04 5.15.0.100.110~20.04.52 linux-image-generic-lpae-hwe-20.04 5.15.0.100.110~20.04.52 linux-image-gkeop-5.15 5.15.0.1038.44~20.04.34 linux-image-ibm 5.15.0.1048.51~20.04.20 linux-image-lowlatency-64k-hwe-20.04 5.15.0.100.110~20.04.49 linux-image-lowlatency-hwe-20.04 5.15.0.100.110~20.04.49 linux-image-oem-20.04 5.15.0.100.110~20.04.52 linux-image-oem-20.04b 5.15.0.100.110~20.04.52 linux-image-oem-20.04c 5.15.0.100.110~20.04.52 linux-image-oem-20.04d 5.15.0.100.110~20.04.52 linux-image-virtual-hwe-20.04 5.15.0.100.110~20.04.52 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.
