CERT-FR advisory CERTFR-2026-AVI-0956 documents multiple vulnerabilities discovered in the Linux kernel used by SUSE. The affected systems span openSUSE Leap, SUSE Linux Enterprise Server, SUSE Linux Enterprise High Performance Computing, SUSE Linux Enterprise Micro, SUSE Linux Enterprise Real Time, and related variants across multiple service packs and versions. The vulnerabilities allow attackers to compromise data confidentiality and integrity, bypass security policies, and cause denial of service. SUSE released coordinated security updates across 17 distinct advisories published between 17–28 July 2026, with patches available through the vendor's update mechanism. Organizations running affected SUSE distributions should prioritize kernel updates to mitigate exposure to these kernel-level flaws.
