What to check
- Applies to
- The 23 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR has published an advisory (CERTFR-2026-AVI-1028) covering multiple vulnerabilities discovered in the Red Hat Enterprise Linux kernel, affecting a broad range of RHEL product lines and architectures including x86_64, ARM64, IBM z Systems, and Power little-endian, across versions 8 through 10.2 and various support tiers (EUS, ELS, AUS, TUS, SAP Solutions). The vulnerabilities collectively allow an attacker to compromise data integrity and confidentiality, bypass security policies, cause remote denial of service, execute arbitrary code, and escalate privileges.
Red Hat has released thirteen separate security errata (RHSA) between August 7 and August 13, 2026, addressing more than 20 distinct CVEs affecting kernel components. No specific exploitation details, proof-of-concept code, or in-the-wild attacks are mentioned in the advisory; it is a standard vendor patch notification distributed by the French national CERT. Organizations running affected RHEL versions should apply the referenced RHSA patches according to their standard patch management processes.
Given the breadth of affected systems and the kernel-level nature of the flaws (which can lead to privilege escalation and code execution), timely patching is recommended, though there is no indication of active exploitation at time of publication.

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.
