> CERT-FR advisory covers multiple Oracle Database Server vulnerabilities enabling remote code execution, denial of service, and data exposure; patches available.

CERT-FR has published an advisory detailing numerous vulnerabilities affecting Oracle Database Server and related components, including Oracle Net Services, Oracle OLAP, and Oracle SQLcl, across versions 19.3-19.32, 21.3-21.23, and 23.4.0-23.26.3. The vulnerabilities stem from Oracle's October 2026 Critical Patch Update (CPU) bulletin and collectively allow attackers to achieve remote code execution, remote denial of service, data confidentiality breaches, data integrity compromise, and security policy bypass.

No in-the-wild exploitation is mentioned in this advisory. Defenders running affected Oracle Database Server versions should consult Oracle's official CPU bulletin (cpuoct2026) for patch details and apply fixes according to their organization's patch management policy, prioritizing systems exposed to untrusted networks given the breadth of impact categories including remote code execution.
