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.
