CERT-FR: Multiple vulnerabilities in the SUSE Linux kernel fixed in October 2026 SUSE bulletins (CERTFR-2026-AVI-1432)
The French CERT-FR published advisory CERTFR-2026-AVI-1432 on 30 October 2026 about multiple vulnerabilities in the SUSE Linux kernel. According to the advisory, an attacker could exploit them to breach data confidentiality, bypass the security policy and cause a denial of service. The advisory covers a very wide range of SUSE Linux Enterprise products (Server, Desktop, High Performance Computing, Real Time, Micro, Live Patching, SAP Applications and others) and cites more than 100 CVEs. It does not mention exploitation in the wild. Fixes are distributed through numerous SUSE security bulletins published between 19 and 29 October 2026.

A vulnerabilidade
CERT-FR advisory CERTFR-2026-AVI-1432 covers more than 100 CVEs in the SUSE Linux kernel, from CVE-2022-50578 to CVE-2026-89593. The advisory gives no CVSS scores and no per-CVE details, so no single flaw can be ranked as the most severe. It says an attacker could breach data confidentiality, bypass the security policy or cause a denial of service. The attack vector and exploitation conditions are not specified by the vendor. Affected products include SUSE Linux Enterprise Server 11 SP4, 12 SP5, 15 SP4 to SP7 and 16.0, the SAP Applications, High Performance Computing, Real Time, Live Patching, Micro, High Availability and Desktop editions, and Manager Retail Branch Server 4.3. The fixes are the kernel updates in the SUSE-SU-2026 bulletins of 19 to 29 October 2026.
Como funciona
The advisory does not describe how any of these flaws work. It gives no input, component or step where the kernel goes wrong, so the mechanism cannot be explained without guessing. The per-CVE details are in the SUSE bulletins and the kernel CVE records, which the advisory points to but does not reproduce.
Por que é vulnerável
The advisory does not state the root cause of any of the CVEs. It only lists the impact categories: confidentiality breach, security policy bypass and denial of service. It also does not say why the flaws went unnoticed. The fix is the updated SUSE kernel packages, but the advisory does not describe what they change.
Como foi descoberta
The articles do not say who found these flaws or how. CERT-FR published the advisory on 30 October 2026, summarizing fixes that SUSE released in many security bulletins between 19 and 29 October 2026. The advisory does not mention exploitation in the wild.
