Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-kvm: Linux kernel for cloud environments - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty Details: It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655) It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33656) Christian Brauner discovered that the XFS file system implementation in the Linux kernel did not properly handle setgid file creation. A local attacker could use this to gain elevated privileges. (CVE-2021-4037) It was discovered that the ext4 file system implementation 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-2022-0850) Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not handle detach events properly in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1199) Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux kernel during device detach operations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1204) Norbert Slusarek discovered that a race condition existed in the perf subsystem in the Linux kernel, resulting in 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-2022-1729) It was discovered that the Packet network protocol implementation in the Linux kernel contained an out-of-bounds access. A remote attacker could use this to expose sensitive information (kernel memory). (CVE-2022-20368) It was discovered that the Open vSwitch implementation in the Linux kernel contained an out of bounds write vulnerability in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2639) Jann Horn discovered that the ASIX AX88179/178A USB Ethernet driver in the Linux kernel contained multiple out-of-bounds vulnerabilities. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2964) Hao Sun and Jiacheng Xu discovered that the NILFS file system implementation in the Linux kernel contained 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-2022-2978) Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-3028) It was discovered that the Journaled File System (JFS) in the Linux kernel contained a null pointer dereference in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3202) Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-36946) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.4.0-1114-kvm 4.4.0-1114.124 linux-image-4.4.0-1151-aws 4.4.0-1151.166 linux-image-4.4.0-234-generic 4.4.0-234.268 linux-image-4.4.0-234-lowlatency 4.4.0-234.268 linux-image-aws 4.4.0.1151.155 linux-image-generic 4.4.0.234.240 linux-image-kvm 4.4.0.1114.111 linux-image-lowlatency 4.4.0.234.240 linux-image-virtual 4.4.0.234.240 Ubuntu 14.04 ESM: linux-image-4.4.0-1113-aws 4.4.0-1113.119 linux-image-4.4.0-234-generic 4.4.0-234.268~14.04.1 linux-image-4.4.0-234-lowlatency 4.4.0-234.268~14.04.1 linux-image-aws 4.4.0.1113.110 linux-image-generic-lts-xenial 4.4.0.234.203 linux-image-lowlatency-lts-xenial 4.4.0.234.203 linux-image-virtual-lts-xenial 4.4.0.234.203 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.
