27.07.2026 18:40 Confidential computing is moving quickly. The foundation is already here: AMD SEV-SNP and Intel TDX have made it possible to run confidential virtual machines with stronger protection for data in use. Ubuntu 26.04 Long Term Support brings integrated host and guest support for both of these technologies, making confidential computing a native part

25.07.2026 00:00 Most organizations already understand encryption at rest and encryption in transit. These controls are mature, widely deployed, and often explicitly referenced in security frameworks. However, runtime is different: when an application processes sensitive information, that data is typically available in memory. In a traditional infrastructure model, the workload owner may need to trust a large

24.07.2026 16:32 Meet Alex, an Android developer. In this article, we’ll follow Alex through their day to show you how Anbox Cloud supports Alex from feature development to release. Alex’s focus for today is building a ride-tracking feature for their ride-sharing app.

21.07.2026 20:40 Canonical introduces a new way to manage software behind firewalls and in air-gapped environments with the Enterprise Store. The Enterprise Store makes software distribution manageable and scalable behind firewalls or in air-gapped environments. Available with an Ubuntu Pro subscription, the Enterprise Store respects the security protocols of strict environments, in a way that is controllable,

18.07.2026 20:51 How Canonical Support helped a global retail organization trace the cause for an unusual memory leak originating in PID 1. By investigating the issue across three separate system layers our team was able to identify the source and fast-track a patch.

14.07.2026 23:30 MAAS brings cloud-like automation to physical servers. It helps teams discover, commission, deploy, and repurpose machines from a central control plane, turning bare metal into a programmable resource. But to experience that value, users first need to get MAAS up and running. That path is now cleaner and easier to follow. We’ve created new documentation

12.07.2026 05:00 Introduction A local privilege escalation vulnerability affecting the Linux kernel was publicly disclosed on July 6, 2026. The vulnerability was assigned CVE ID CVE-2026-53359 and is referred to as Januscape. This vulnerability affects all Ubuntu releases. Neither NVD nor Kernel.org have published their own CVSS scores for this issue; we calculated it as CVSS

09.07.2026 23:41 Modern infrastructure teams are expected to deliver cloud-like speed, consistency, and reliability, even when their workloads run on physical servers. Bare metal remains essential for many environments: private clouds, Kubernetes clusters, AI infrastructure, edge sites, regulated platforms, and large Ubuntu estates. But operating physical infrastructure at scale is difficult when provisioning, patching, monitoring, and lifecycle

08.07.2026 00:10 A platform is an environment that allows software to run smoothly across the infrastructure, runtime, and application layers. The key word there is “smoothly”: a good platform connects those layers so well that you don’t notice it. That’s what Ubuntu Server has become: the essential layer between bare metal and the apps running on top,

07.07.2026 05:00 Canonical is pleased to share its latest research report, “The open source chain of trust.” Based on a survey of 500 DevOps professionals, the report highlights how organizations approach their open source software supply chains. While many companies are moving toward verifiable provenance and automated security workflows, internal misalignment and disjointed approaches remain serious challenges

06.07.2026 22:21 In the traditional automotive world, teams often work in silos: the cybersecurity experts lock down the ports, the quality assurance teams hunt for bugs, and the functional safety engineers track the ISO 26262 compliance. At Canonical, we believe this fragmented workflow causes friction rather than collaboration.

03.07.2026 00:10 On June 25, 2026, JFrog published their research into CVE-2026-43503, referring to the vulnerability as DirtyClone. The vulnerability had previously been responsibly disclosed to the Linux kernel maintainers and the CVE record published on May 23, 2026. The vulnerability affects multiple Linux distributions, including all Ubuntu releases. The first security updates for Ubuntu were released

02.07.2026 18:10 Mitigations are available for the Linux vulnerability with CVE ID CVE-2026-46331. The CVE ID was assigned on June 16 2026 and highlighted as a local privilege escalation vulnerability on June 26, 2026. Known as “pedit COW”, this vulnerability affects multiple Linux distributions, including all Ubuntu releases starting with Bionic Beaver 18.04 LTS. Ubuntu Resolute

02.07.2026 11:20 Canonical is pleased to announce it is now a Gold Sponsor of the Trifecta Tech Foundation, a non-profit that creates open source building blocks for critical infrastructure software. Canonical has supported the foundation’s work since 2025, co-sponsoring the development of projects like sudo-rs. The new €40,000/year contribution will help the foundation continue developing and maintaining
