Red Hat has published multiple security advisories addressing 44 vulnerabilities in the Linux kernel affecting Red Hat Enterprise Linux (RHEL) versions 8, 9, and 10 across multiple architectures (x86_64, aarch64, s390x, ppc64le), as well as Red Hat OpenShift Container Platform versions 4.18 through 4.21. The vulnerabilities span from 2023 to 2026, indicating a comprehensive kernel security update cycle.
The flaws enable various attack vectors including remote arbitrary code execution, privilege escalation, denial of service, security policy bypass, and data confidentiality and integrity compromise. The advisories were released between June 12-17, 2026, covering extended life cycle, extended update support, and real-time variants of RHEL, as well as OpenShift deployments across multiple processor architectures.
Red Hat recommends that affected organizations apply the patches as detailed in the security bulletins. Given the broad deployment of RHEL in enterprise environments and the range of impacts including remote code execution, timely patching is essential for organizations running these platforms.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
