Exploitation
No exploitation in the wild and no public exploit is recorded for the CVEs named.

CERT-FR has published an advisory covering multiple vulnerabilities discovered in the Linux kernel used across SUSE product lines. The affected products span a broad range including openSUSE Leap 15.5 and 15.6, SUSE Linux Enterprise Server editions (11 SP4 through 15 SP6), SUSE Linux Enterprise Micro variants (5.3 through 6.2), and specialized deployments such as High Availability Extension, Live Patching, Real Time, and SAP Applications versions. The vulnerabilities collectively pose risks including arbitrary code execution, data confidentiality compromise, data integrity violations, security policy bypass, and denial of service. SUSE has released coordinated security bulletins addressing these flaws across multiple update announcements issued between June 1 and June 10, 2026. Defenders operating any affected SUSE Linux variant should prioritize applying the corresponding patches immediately given the severity of the potential impacts.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.

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.
