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-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-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - 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-gke-5.4: Linux kernel for Google Container Engine (GKE) systems - linux-gkeop-5.4: Linux kernel for Google Container Engine (GKE) 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: Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2588) It was discovered that the netfilter subsystem of the Linux kernel did not prevent one nft object from referencing an nft set in another nft table, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2586) It was discovered that the block layer subsystem in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0494) Hu Jiahui discovered that multiple race conditions existed in the Advanced Linux Sound Architecture (ALSA) framework, leading to use-after-free vulnerabilities. A local attacker could use these to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1048) Minh Yuan discovered that the floppy disk driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1652) It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, 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-2022-1679) It was discovered that the Marvell NFC device driver implementation in the Linux kernel did not properly perform memory cleanup operations in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1734) Duoming Zhou discovered a race condition in the NFC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1974) Duoming Zhou discovered that the NFC subsystem in the Linux kernel did not properly prevent context switches from occurring during certain atomic context operations. A privileged local attacker could use this to cause a denial of service (system crash). (CVE-2022-1975) Felix Fu discovered that the Sun RPC implementation in the Linux kernel did not properly handle socket states, leading to a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-28893) Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel did not properly perform data validation. A local attacker could use this to escalate privileges in certain situations. (CVE-2022-34918) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.4.0-1031-ibm 5.4.0-1031.35 linux-image-5.4.0-1044-bluefield 5.4.0-1044.49 linux-image-5.4.0-1051-gkeop 5.4.0-1051.54 linux-image-5.4.0-1068-raspi 5.4.0-1068.78 linux-image-5.4.0-1073-kvm 5.4.0-1073.78 linux-image-5.4.0-1080-gke 5.4.0-1080.86 linux-image-5.4.0-1081-oracle 5.4.0-1081.89 linux-image-5.4.0-1083-aws 5.4.0-1083.90 linux-image-5.4.0-1086-gcp 5.4.0-1086.94 linux-image-5.4.0-1089-azure 5.4.0-1089.94 linux-image-5.4.0-124-generic 5.4.0-124.140 linux-image-5.4.0-124-generic-lpae 5.4.0-124.140 linux-image-5.4.0-124-lowlatency 5.4.0-124.140 linux-image-aws-lts-20.04 5.4.0.1083.83 linux-image-azure-lts-20.04 5.4.0.1089.86 linux-image-bluefield 5.4.0.1044.43 linux-image-gcp-lts-20.04 5.4.0.1086.91 linux-image-generic 5.4.0.124.125 linux-image-generic-lpae 5.4.0.124.125 linux-image-gke 5.4.0.1080.88 linux-image-gke-5.4 5.4.0.1080.88 linux-image-gkeop 5.4.0.1051.52 linux-image-gkeop-5.4 5.4.0.1051.52 linux-image-ibm 5.4.0.1031.60 linux-image-ibm-lts-20.04 5.4.0.1031.60 linux-image-kvm 5.4.0.1073.70 linux-image-lowlatency 5.4.0.124.125 linux-image-oem 5.4.0.124.125 linux-image-oem-osp1 5.4.0.124.125 linux-image-oracle-lts-20.04 5.4.0.1081.78 linux-image-raspi 5.4.0.1068.101 linux-image-raspi2 5.4.0.1068.101 linux-image-virtual 5.4.0.124.125 Ubuntu 18.04 LTS: linux-image-5.4.0-1031-ibm 5.4.0-1031.35~18.04.1 linux-image-5.4.0-1051-gkeop 5.4.0-1051.54~18.04.1 linux-image-5.4.0-1068-raspi 5.4.0-1068.78~18.04.1 linux-image-5.4.0-1080-gke 5.4.0-1080.86~18.04.1 linux-image-5.4.0-1081-oracle 5.4.0-1081.89~18.04.1 linux-image-5.4.0-1083-aws 5.4.0-1083.90~18.04.1 linux-image-5.4.0-1086-gcp 5.4.0-1086.94~18.04.1 linux-image-5.4.0-1089-azure 5.4.0-1089.94~18.04.1 linux-image-5.4.0-124-generic 5.4.0-124.140~18.04.1 linux-image-5.4.0-124-generic-lpae 5.4.0-124.140~18.04.1 linux-image-5.4.0-124-lowlatency 5.4.0-124.140~18.04.1 linux-image-aws 5.4.0.1083.63 linux-image-azure 5.4.0.1089.66 linux-image-gcp 5.4.0.1086.65 linux-image-generic-hwe-18.04 5.4.0.124.140~18.04.104 linux-image-generic-lpae-hwe-18.04 5.4.0.124.140~18.04.104 linux-image-gke-5.4 5.4.0.1080.86~18.04.42 linux-image-gkeop-5.4 5.4.0.1051.54~18.04.48 linux-image-ibm 5.4.0.1031.45 linux-image-lowlatency-hwe-18.04 5.4.0.124.140~18.04.104 linux-image-oem 5.4.0.124.140~18.04.104 linux-image-oem-osp1 5.4.0.124.140~18.04.104 linux-image-oracle 5.4.0.1081.89~18.04.58 linux-image-raspi-hwe-18.04 5.4.0.1068.68 linux-image-snapdragon-hwe-18.04 5.4.0.124.140~18.04.104 linux-image-virtual-hwe-18.04 5.4.0.124.140~18.04.104 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.
