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...

In this article, you’ll learn about the Performance Co-Pilot (PCP) tool and how we take advantage of it to implement system and application monitoring for Red Hat Ansible Automation Platform.What is Performance Co-Pilot (PCP)PCP is an open source performance monitoring and analysis framework developed by Red Hat. It provides a suite of tools, libraries and services to monitor, retrieve and analyze performance metrics from different systems, services and applications. PCP is designed for scalability, enabling it to monitor anything from a single server to a large, distributed network of machi

Red Hat Security Advisory 2024-10517-03 - Red Hat OpenShift Container Platform release 4.17.7 is now available with updates to packages and images that fix several bugs.

Security is important in enterprise scenarios, where core business applications need to run seamlessly but are often connected to the external world where they are vulnerable to attack.Malware, unauthorized access to files and execution of unverified code are just some examples of how system security can be compromised, not only by exploiting known bugs and vulnerabilities, but also by the lack of appropriate countermeasures.Red Hat Enterprise Linux (RHEL) can help, as it provides some tools and services that can natively support the process of system hardening to help make your system more se
