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

CERT-FR (French national cybersecurity authority) has published a security advisory documenting multiple vulnerabilities discovered in the Linux kernel as shipped by SUSE. The affected systems span a wide range of SUSE products including SUSE Linux Enterprise Server (15 SP5-SP7 and variants), SUSE Linux Enterprise Desktop, openSUSE Leap (15.5-15.6), SUSE Linux Micro, and various specialized modules (High Availability, Real Time, Live Patching). The vulnerabilities permit attackers to compromise data confidentiality and integrity, bypass security policies, and cause denial of service. SUSE has released kernel updates across 27 separate security bulletins dated July 2026 to address these issues. The advisory references over 180 CVEs affecting the kernel, indicating a substantial patch campaign. The actual exploit status and specific attack vectors for individual CVEs are not detailed in this advisory summary; defenders should consult the corresponding SUSE security bulletins for kernel version information and patch availability.
