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.
ANSSI/CERT-FR relayed a Red Hat security advisory covering a large batch of vulnerabilities affecting the Linux kernel across nearly all Red Hat Enterprise Linux product lines and architectures (x86_64, aarch64, ppc64le, s390x), spanning RHEL 8, 9, and 10 as well as CodeReady Linux Builder variants and various support tiers (EUS, ELS, AUS, SAP Update Services).
The advisory bundles over 20 CVEs disclosed across 2025 and 2026, with impacts ranging from arbitrary code execution and privilege escalation to remote denial of service and unauthorized disclosure of information, along with potential security policy bypass. No public exploitation or proof-of-concept details are mentioned in the source; this is a routine vendor patch aggregation notice. Red Hat has published 18 separate RHSA errata between July 31 and August 7, 2026, each addressing subsets of the affected products. Administrators running any RHEL-based systems should prioritize patching according to the referenced RHSA bulletins, particularly given the breadth of impacted product lines and the presence of privilege escalation and RCE vectors within the kernel.

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.
