========================================================================== Ubuntu Security Notice USN-6172-1 June 16, 2023 linux, linux-aws, linux-aws-5.15, linux-azure, linux-azure-5.15, linux-azure-fde-5.15, linux-gcp, linux-gcp-5.15, linux-gke, linux-gke-5.15, linux-gkeop, linux-hwe-5.15, linux-ibm, linux-kvm, linux-lowlatency, linux-lowlatency-hwe-5.15, linux-oracle, linux-oracle-5.15, linux-raspi 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-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-lowlatency: Linux low latency kernel - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) 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-gke-5.15: Linux kernel for Google Container Engine (GKE) systems - linux-hwe-5.15: Linux hardware enablement (HWE) kernel - linux-lowlatency-hwe-5.15: Linux low latency kernel - linux-oracle-5.15: Linux kernel for Oracle Cloud systems Details: It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1076) It was discovered that the Real-Time Scheduling Class implementation 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-2023-1077) It was discovered that the ASUS HID driver in the Linux kernel did not properly handle device removal, leading to a use-after-free vulnerability. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash). (CVE-2023-1079) It was discovered that the Xircom PCMCIA network device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1670) It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2023-1859) Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2 mitigations with prctl syscall were insufficient in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2023-1998) It was discovered that the BigBen Interactive Kids' gamepad driver in the Linux kernel did not properly handle device removal, leading to a use- after-free vulnerability. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash). (CVE-2023-25012) It was discovered that a use-after-free vulnerability existed in the HFS+ file system implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-2985) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.15.0-1022-gkeop 5.15.0-1022.27 linux-image-5.15.0-1032-ibm 5.15.0-1032.35 linux-image-5.15.0-1032-raspi 5.15.0-1032.35 linux-image-5.15.0-1032-raspi-nolpae 5.15.0-1032.35 linux-image-5.15.0-1035-kvm 5.15.0-1035.40 linux-image-5.15.0-1036-gcp 5.15.0-1036.44 linux-image-5.15.0-1036-gke 5.15.0-1036.41 linux-image-5.15.0-1037-oracle 5.15.0-1037.43 linux-image-5.15.0-1038-aws 5.15.0-1038.43 linux-image-5.15.0-1040-azure 5.15.0-1040.47 linux-image-5.15.0-75-generic 5.15.0-75.82 linux-image-5.15.0-75-generic-64k 5.15.0-75.82 linux-image-5.15.0-75-generic-lpae 5.15.0-75.82 linux-image-5.15.0-75-lowlatency 5.15.0-75.82 linux-image-5.15.0-75-lowlatency-64k 5.15.0-75.82 linux-image-aws-lts-22.04 5.15.0.1038.37 linux-image-azure 5.15.0.1040.36 linux-image-azure-lts-22.04 5.15.0.1040.36 linux-image-gcp-lts-22.04 5.15.0.1036.32 linux-image-generic 5.15.0.75.73 linux-image-generic-64k 5.15.0.75.73 linux-image-generic-lpae 5.15.0.75.73 linux-image-gke 5.15.0.1036.35 linux-image-gke-5.15 5.15.0.1036.35 linux-image-gkeop 5.15.0.1022.21 linux-image-gkeop-5.15 5.15.0.1022.21 linux-image-ibm 5.15.0.1032.28 linux-image-kvm 5.15.0.1035.31 linux-image-lowlatency 5.15.0.75.80 linux-image-lowlatency-64k 5.15.0.75.80 linux-image-oracle 5.15.0.1037.32 linux-image-raspi 5.15.0.1032.29 linux-image-raspi-nolpae 5.15.0.1032.29 linux-image-virtual 5.15.0.75.73 Ubuntu 20.04 LTS: linux-image-5.15.0-1036-gcp 5.15.0-1036.44~20.04.1 linux-image-5.15.0-1036-gke 5.15.0-1036.41~20.04.1 linux-image-5.15.0-1037-oracle 5.15.0-1037.43~20.04.1 linux-image-5.15.0-1038-aws 5.15.0-1038.43~20.04.1 linux-image-5.15.0-1040-azure 5.15.0-1040.47~20.04.1 linux-image-5.15.0-1040-azure-fde 5.15.0-1040.47~20.04.1.1 linux-image-5.15.0-75-generic 5.15.0-75.82~20.04.1 linux-image-5.15.0-75-generic-64k 5.15.0-75.82~20.04.1 linux-image-5.15.0-75-generic-lpae 5.15.0-75.82~20.04.1 linux-image-5.15.0-75-lowlatency 5.15.0-75.82~20.04.1 linux-image-5.15.0-75-lowlatency-64k 5.15.0-75.82~20.04.1 linux-image-5.4.0-152-generic 5.4.0-152.169 linux-image-5.4.0-152-generic-lpae 5.4.0-152.169 linux-image-5.4.0-152-lowlatency 5.4.0-152.169 linux-image-aws 5.15.0.1038.43~20.04.27 linux-image-azure 5.15.0.1040.47~20.04.30 linux-image-azure-cvm 5.15.0.1040.47~20.04.30 linux-image-azure-fde 5.15.0.1040.47~20.04.1.19 linux-image-gcp 5.15.0.1036.44~20.04.1 linux-image-generic 5.4.0.152.149 linux-image-generic-64k-hwe-20.04 5.15.0.75.82~20.04.36 linux-image-generic-hwe-20.04 5.15.0.75.82~20.04.36 linux-image-generic-lpae 5.4.0.152.149 linux-image-generic-lpae-hwe-20.04 5.15.0.75.82~20.04.36 linux-image-gke-5.15 5.15.0.1036.41~20.04.1 linux-image-lowlatency 5.4.0.152.149 linux-image-lowlatency-64k-hwe-20.04 5.15.0.75.82~20.04.33 linux-image-lowlatency-hwe-20.04 5.15.0.75.82~20.04.33 linux-image-oem 5.4.0.152.149 linux-image-oem-20.04 5.15.0.75.82~20.04.36 linux-image-oem-20.04b 5.15.0.75.82~20.04.36 linux-image-oem-20.04c 5.15.0.75.82~20.04.36 linux-image-oem-20.04d 5.15.0.75.82~20.04.36 linux-image-oem-osp1 5.4.0.152.149 linux-image-oracle 5.15.0.1037.43~20.04.1 linux-image-virtual 5.4.0.152.149 linux-image-virtual-hwe-20.04 5.15.0.75.82~20.04.36 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.
