What to check
- Applies to
- The 40 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 published a bulletin consolidating a very large number of vulnerabilities affecting the Linux kernel as shipped across nearly the entire SUSE product portfolio, including SUSE Linux Enterprise Server, Desktop, High Availability, High Performance Computing, Real Time, Live Patching, SUSE Linux Enterprise Micro, and openSUSE Leap releases spanning versions 12 SP5 through 15 SP7 and 6.0. The advisory aggregates dozens of individual SUSE security update announcements (SUSE-SU-2026:xxxx series) issued between late October and early November 2026, each addressing a subset of the listed CVEs.
The vulnerabilities collectively allow an attacker to impact data confidentiality, data integrity, bypass security policy, or cause denial of service, consistent with typical Linux kernel flaw classes (use-after-free, out-of-bounds access, race conditions, NULL pointer dereference, etc.) found across kernel subsystems. No single flaw is detailed with exploitation specifics in this bulletin, and CERT-FR does not indicate active in-the-wild exploitation; this is a routine vendor patch aggregation advisory.
Defenders running any SUSE-based Linux distribution should prioritize applying the referenced SUSE-SU update packages as identified by their product and service pack level. Given the sheer volume of CVEs and the breadth of affected SUSE product lines (including SAP application servers and HPC/real-time variants), organizations should treat this as a standard but comprehensive kernel patch cycle and schedule testing and rollout according to normal change-management processes, prioritizing internet-facing or multi-tenant systems where kernel-level confidentiality/integrity bypass would be most impactful.

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.
