Canonical Livepatch now officially supports Arm64, further expanding its security patching automation capabilities. For the first time, Ubuntu on an Arm64 machine can apply critical kernel updates, without service interruption or rebooting. Starting with Ubuntu Core 26 for Arm64, and for Ubuntu Core 20 and onwards for AMD64 machines, a wi
The purpose of this article is to share the technical realities of security patching for the Linux kernel, and the intended scope of the Linux kernel’s livepatch capability. We’ll cover when kernel live patching is most appropriate, and when updating deb and snap packages and then rebooting is the best option.
In internet connected environments, where Ubuntu instances can reach livepatch.canonical.com, Livepatch Client supports timestamp-based rollout configurations. Organizations can implement controlled and predictable update pipelines from staging to production environments, without the hassle of deploying a self-hosted Livepatch Server, and
The kernel engineering team at Canonical has generated a new module signing certificate on May 16, 2025, and it is embedded in all Ubuntu kernels published after that date. Livepatch Client version 10.11.2 published on June 13, 2025 includes this new certificate. Livepatch Client 10.11.2 or greater is required to successfully Livepatch al
What safeguards the Livepatch security patching solution against bad actors and malicious code masquerading as an update? Learn about Secure Boot and module signing.
To start securely and efficiently, Linux systems follow a carefully orchestrated sequence of steps to initialize firmware and manage services. Applying security patches to the software responsible for some of these early steps of Linux startup often requires a full system reboot. Frequent reboots driven by unplanned critical patching is d
Deploying FreePBX and Asterisk on a single Ubuntu virtual machine in a public cloud is an ideal solution for personal users and small to medium-sized businesses with voice over IP (VoIP) and fax over IP (FoIP) needs. This setup costs nothing, is scalable and secure, and has daily recovery points with a recovery time measured

라이브패치는 시스템을 즉시 재부팅할 필요 없고 런타임에 중요하고 높은 보안 커널 공통 보안 취약성 및 노출(CVE)을 수정하는 유용한 툴입니다. 그러나 정기적인 유지 관리 기간 및 재부팅을 대체하는 용도로 사용해서는 안 됩니다. 좋은 기업 정책에는 시스템이 안정적이고 안전하게 유지되도록 라이브패치와 정기적인 재부팅이 모두 포함되어야 합니다. 그 이유는 펌웨어 또는 장치 드라이버 업데이트와 같은 일부 시스템 CVE는
The Livepatch tool is a valuable solution for resolving critical and high-security kernel CVEs without requiring an immediate system reboot. However, it is not a substitute for regular maintenance windows and reboots, as some CVEs still require a system reboot. Additionally, Livepatch only covers security-related kernel updates, not non-s
Livepatch allows Ubuntu users to fix critical and high kernel vulnerabilities at runtime, which reduces the need for unplanned reboots. Until now, Livepatch has only been available for Long-Term Release (LTS) kernels, but starting with the release of Ubuntu’s interim release of 23.04 Lunar Lobster in April 2023, it will also be available

In August 2016, the United States government announced a new federal source-code policy, which mandates that at least 20% of custom source code developed by or for any agency of the federal government must be released as open-source software (OSS). The memo of this policy also states that the Federal Government spends more than $6
