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-gkeop: Linux kernel for Google Container Engine (GKE) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-intel-iotg: Linux kernel for Intel IoT platforms - linux-kvm: Linux kernel for cloud environments - linux-lowlatency: Linux low latency kernel - linux-nvidia: Linux kernel for NVIDIA systems - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi 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: Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-47233) 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: - MAC80211 subsystem; - Tomoyo security module; (CVE-2024-26622, CVE-2023-52530) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1045-gkeop 5.15.0-1045.52 linux-image-5.15.0-1055-ibm 5.15.0-1055.58 linux-image-5.15.0-1055-nvidia 5.15.0-1055.56 linux-image-5.15.0-1055-nvidia-lowlatency 5.15.0-1055.56 linux-image-5.15.0-1055-raspi 5.15.0-1055.58 linux-image-5.15.0-1057-intel-iotg 5.15.0-1057.63 linux-image-5.15.0-1059-kvm 5.15.0-1059.64 linux-image-5.15.0-1060-gcp 5.15.0-1060.68 linux-image-5.15.0-1060-oracle 5.15.0-1060.66 linux-image-5.15.0-1064-azure 5.15.0-1064.73 linux-image-5.15.0-1064-azure-fde 5.15.0-1064.73.1 linux-image-5.15.0-107-generic 5.15.0-107.117 linux-image-5.15.0-107-generic-64k 5.15.0-107.117 linux-image-5.15.0-107-generic-lpae 5.15.0-107.117 linux-image-5.15.0-107-lowlatency 5.15.0-107.117 linux-image-5.15.0-107-lowlatency-64k 5.15.0-107.117 linux-image-azure-fde-lts-22.04 5.15.0.1064.73.42 linux-image-azure-lts-22.04 5.15.0.1064.62 linux-image-gcp-lts-22.04 5.15.0.1060.56 linux-image-generic 5.15.0.107.107 linux-image-generic-64k 5.15.0.107.107 linux-image-generic-lpae 5.15.0.107.107 linux-image-gkeop 5.15.0.1045.44 linux-image-gkeop-5.15 5.15.0.1045.44 linux-image-ibm 5.15.0.1055.51 linux-image-intel-iotg 5.15.0.1057.57 linux-image-kvm 5.15.0.1059.55 linux-image-lowlatency 5.15.0.107.102 linux-image-lowlatency-64k 5.15.0.107.102 linux-image-nvidia 5.15.0.1055.55 linux-image-nvidia-lowlatency 5.15.0.1055.55 linux-image-oracle-lts-22.04 5.15.0.1060.56 linux-image-raspi 5.15.0.1055.53 linux-image-raspi-nolpae 5.15.0.1055.53 linux-image-virtual 5.15.0.107.107 Ubuntu 20.04 LTS linux-image-5.15.0-1045-gkeop 5.15.0-1045.52~20.04.1 linux-image-5.15.0-1055-ibm 5.15.0-1055.58~20.04.1 linux-image-5.15.0-1060-gcp 5.15.0-1060.68~20.04.1 linux-image-5.15.0-1064-azure 5.15.0-1064.73~20.04.1 linux-image-5.15.0-1064-azure-fde 5.15.0-1064.73~20.04.1.1 linux-image-5.15.0-107-generic 5.15.0-107.117~20.04.1 linux-image-5.15.0-107-generic-64k 5.15.0-107.117~20.04.1 linux-image-5.15.0-107-generic-lpae 5.15.0-107.117~20.04.1 linux-image-5.15.0-107-lowlatency 5.15.0-107.117~20.04.1 linux-image-5.15.0-107-lowlatency-64k 5.15.0-107.117~20.04.1 linux-image-azure 5.15.0.1064.73~20.04.1 linux-image-azure-cvm 5.15.0.1064.73~20.04.1 linux-image-azure-fde 5.15.0.1064.73~20.04.1.42 linux-image-gcp 5.15.0.1060.68~20.04.1 linux-image-generic-64k-hwe-20.04 5.15.0.107.117~20.04.1 linux-image-generic-hwe-20.04 5.15.0.107.117~20.04.1 linux-image-generic-lpae-hwe-20.04 5.15.0.107.117~20.04.1 linux-image-gkeop-5.15 5.15.0.1045.52~20.04.1 linux-image-ibm 5.15.0.1055.58~20.04.1 linux-image-lowlatency-64k-hwe-20.04 5.15.0.107.117~20.04.1 linux-image-lowlatency-hwe-20.04 5.15.0.107.117~20.04.1 linux-image-oem-20.04 5.15.0.107.117~20.04.1 linux-image-oem-20.04b 5.15.0.107.117~20.04.1 linux-image-oem-20.04c 5.15.0.107.117~20.04.1 linux-image-oem-20.04d 5.15.0.107.117~20.04.1 linux-image-virtual-hwe-20.04 5.15.0.107.117~20.04.1 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.
