The French CERT (CERT-FR) published an advisory detailing multiple vulnerabilities discovered in the Red Hat Enterprise Linux kernel affecting versions 7 through 10 across all architectures. The flaws impact Red Hat Enterprise Linux and CodeReady Linux Builder distributions for ARM64, x86_64, IBM z Systems, and Power architectures, including Extended Update Support and Extended Life Cycle versions.
The vulnerabilities enable several attack vectors including remote arbitrary code execution, privilege escalation, denial of service, security policy bypass, and compromise of data integrity and confidentiality. Red Hat released six security bulletins between June 10-11, 2026 addressing the issues through kernel updates. The advisory references 34 CVE identifiers spanning from 2023 to 2026, indicating both legacy flaws and recently discovered issues.
Organizations running any Red Hat Enterprise Linux version should prioritize applying the vendor-supplied patches immediately given the severity of remote code execution capabilities and the broad attack surface across enterprise deployments.

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.
