The future of conflict is cheap, rapidly manufactured, and tough to defend against.

Last month, we launched Red Hat Ansible Automation Platform 2.6, and introduced several new features including an automation dashboard, a self-service automation portal, and the Ansible Lightspeed intelligent assistant. We hosted a follow-up webinar, What’s new with Ansible Automation Platform 2.6, during which we received some great questions from the audience about how to install, migrate, and upgrade to the latest version. To help you prepare for and navigate the Ansible Automation Platform 2.6 release, we've compiled the top questions and their answers.Installations, upgrades, and migrat

In this October roundup, we cut through the noise to focus on the essential technical blueprints and policy foundations required to succeed. These articles, from key platform updates and critical security integrations to the future of open source legality, represent the core strategic reading for Q4. We highlight how Red Hat Ansible Automation Platform 2.6 streamlines operations, how Red Hat AI 3 and its intelligent control plane transform GPU infrastructure, and how our strategic partnership with NVIDIA simplifies the AI software stack. This is the quarter for planning that prepares your orga

Standardizing your company’s operating environment starts with the operating system (OS), but it doesn’t end there. As the number of systems grows, configurations drift, maintenance becomes repetitive, and updates can quickly turn into a headache. At Red Hat, we support your standardization journey by providing you with what you need to deliver a robust, coherent, and integrated solution for your standard operating environment.In this post, I explore the key areas you should take into account along your standardization journey, and how these can be simplified using Red Hat technologies, pr

The new major release of Red Hat Enterprise Linux (RHEL) brings a number of important improvements in the confidential computing domain. This article covers the most important features available now in both RHEL 10 and RHEL 9.6: Full support for RHEL Unified Kernel Image (UKI), including FIPS and kdump supportIntel Trusted Domain Extension (TDX) guestsTrustee attestation clientFull support for RHEL Unified Kernel Image (UKI)First introduced in RHEL9.2 as a Technology Preview, UKI for RHEL is a UEFI Portable Executable (PE) binary containing the Linux kernel, initramfs, and kernel command line.

In their article on post-quantum cryptography, Emily Fox and Simo Sorce explained how Red Hat is integrating post-quantum cryptography (PQC) into our products. PQC protects confidentiality, integrity and authenticity of communication and data against quantum computers, which will make attacks on existing classic cryptographic algorithms such as RSA and elliptic curves feasible. Cryptographically relevant quantum computers (CRQCs) are not known to exist yet, but continued advances in research point to a future risk of successful attacks. While the migration to algorithms resistant against such

A flaw was found in Yggdrasil, which acts as a system broker, allowing the processes to communicate to other children's "worker" processes through the DBus component. Yggdrasil creates a DBus method to dispatch messages to workers. However, it misses authentication and authorization checks, allowing every system user to call it. One available Yggdrasil worker acts as a package manager with capabilities to create and enable new repositories and install or remove packages. This flaw allows an attacker with access to the system to leverage the lack of authentication on the dispatch message to force the Yggdrasil worker to install arbitrary RPM packages. This issue results in local privilege escalation, enabling the attacker to access and modify sensitive system data.

### Impact Zincati ships a polkit rule which allows the `zincati` system user to use the following actions: - `org.projectatomic.rpmostree1.deploy`: used to deploy updates to the system - `org.projectatomic.rpmostree1.finalize-deployment`: used to reboot the system into the deployed update Since Zincati [v0.0.24](https://github.com/coreos/zincati/releases/tag/v0.0.24), this polkit rule contains a logic error which broadens access of those polkit actions to any unprivileged user rather than just the `zincati` system user. In practice, this means that any unprivileged user with access to the system D-Bus socket is able to deploy older Fedora CoreOS versions (which may have other known vulnerabilities). Note that rpm-ostree enforces that the selected version must be from the same branch the system is currently on so this cannot directly be used to deploy an attacker-controlled update payload. This primarily impacts users running untrusted workloads with access to the system D-Bus sock...
