--- title: 'USN-5518-1: Linux kernel vulnerabilities | Ubuntu security notices' description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/notices/USN-5518-1 --- 1. [Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-5518-1 --- # USN-5518-1: Linux kernel vulnerabilities Publication date 14 July 2022 Overview Several security issues were fixed in the Linux kernel. Releases [22.04 LTS](https://ubuntu.com/security/notices?release=jammy) --- Open side navigation ## Packages * [linux](https://ubuntu.com/security/cves?package=linux) - Linux kernel * [linux-aws](https://ubuntu.com/security/cves?package=linux-aws) - Linux kernel for Amazon Web Services (AWS) systems * [linux-azure](https://ubuntu.com/security/cves?package=linux-azure) - Linux kernel for Microsoft Azure Cloud systems * [linux-gcp](https://ubuntu.com/security/cves?package=linux-gcp) - Linux kernel for Google Cloud Platform (GCP) systems * [linux-gke](https://ubuntu.com/security/cves?package=linux-gke) - Linux kernel for Google Container Engine (GKE) systems * [linux-ibm](https://ubuntu.com/security/cves?package=linux-ibm) - Linux kernel for IBM cloud systems * [linux-kvm](https://ubuntu.com/security/cves?package=linux-kvm) - Linux kernel for cloud environments * [linux-lowlatency](https://ubuntu.com/security/cves?package=linux-lowlatency) - Linux low latency kernel * [linux-oracle](https://ubuntu.com/security/cves?package=linux-oracle) - Linux kernel for Oracle Cloud systems * [linux-raspi](https://ubuntu.com/security/cves?package=linux-raspi) - Linux kernel for Raspberry Pi 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](https://ubuntu.com/security/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 crash) or execute arbitrary code. ([CVE-2022-1734](https://ubuntu.com/security/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 (system crash)... --- Show more ## Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. [Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security) 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. The problem can be corrected by updating your system to the following package versions: | Ubuntu Release | Package Version | | --- | --- | | 22.04 LTS jammy |
