Releases o Ubuntu 22.04 LTS Packages o linux - Linux kernel o linux-aws - Linux kernel for Amazon Web Services (AWS) systems o linux-azure - Linux kernel for Microsoft Azure Cloud systems o linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems o linux-gke - Linux kernel for Google Container Engine (GKE) systems o linux-ibm - Linux kernel for IBM cloud systems o linux-kvm - Linux kernel for cloud environments o linux-lowlatency - Linux low latency kernel o linux-oracle - Linux kernel for Oracle Cloud systems Details It was discovered that the eBPF implementation in the Linux kernel did not properly prevent writes to kernel objects in BPF_BTF_LOAD commands. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. ( CVE-2022-0500 ) 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) or execute arbitrary code. ( CVE-2022-1734 ) Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to cause a denial of service in the host OS (system crash). ( CVE-2022-1789 ) 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 ) Minh Yuan discovered that the floppy driver in the Linux kernel contained a race condition in some situations, 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-2022-33981 ) Update instructions The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 o linux-image-virtual - 5.15.0.41.43 o linux-image-5.15.0-1013-gcp - 5.15.0-1013.18 o linux-image-generic - 5.15.0.41.43 o linux-image-5.15.0-41-generic-64k - 5.15.0-41.44 o linux-image-aws - 5.15.0.1015.15 o linux-image-gke-5.15 - 5.15.0.1011.14 o linux-image-gke - 5.15.0.1011.14 o linux-image-lowlatency-hwe-22.04 - 5.15.0.41.40 o linux-image-ibm - 5.15.0.1010.9 o linux-image-lowlatency-64k - 5.15.0.41.40 o linux-image-generic-hwe-22.04 - 5.15.0.41.43 o linux-image-5.15.0-1013-oracle - 5.15.0-1013.17 o linux-image-5.15.0-41-lowlatency-64k - 5.15.0-41.44 o linux-image-5.15.0-1015-aws - 5.15.0-1015.19 o linux-image-5.15.0-1010-ibm - 5.15.0-1010.12 o linux-image-5.15.0-41-lowlatency - 5.15.0-41.44 o linux-image-azure - 5.15.0.1014.13 o linux-image-oem-20.04 - 5.15.0.41.43 o linux-image-5.15.0-1011-gke - 5.15.0-1011.14 o linux-image-kvm - 5.15.0.1013.11 o linux-image-gcp - 5.15.0.1013.11 o linux-image-5.15.0-1013-kvm - 5.15.0-1013.16 o linux-image-5.15.0-41-generic - 5.15.0-41.44 o linux-image-oracle - 5.15.0.1013.11 o linux-image-generic-64k - 5.15.0.41.43 o linux-image-virtual-hwe-22.04 - 5.15.0.41.43 o linux-image-generic-64k-hwe-22.04 - 5.15.0.41.43 o linux-image-5.15.0-1014-azure - 5.15.0-1014.17 o linux-image-5.15.0-41-generic-lpae - 5.15.0-41.44 o linux-image-generic-lpae - 5.15.0.41.43 o linux-image-generic-lpae-hwe-22.04 - 5.15.0.41.43 o linux-image-lowlatency-64k-hwe-22.04 - 5.15.0.41.40 o linux-image-lowlatency - 5.15.0.41.40 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.
