CVE-2025-36184Network attack vector

Root code execution by instance owners

Published Jan 30, 2026 · Updated Jan 30, 2026

Privilege escalation in IBM Db2 11.5.0 through 11.5.9 for Linux allows remote authenticated users to execute malicious code as root. IBM has not disclosed which privileged Db2 component executes attacker-controlled code or how its excessive privilege becomes exploitable. A Db2 instance-owner account is required; successful exploitation grants root-level code execution on the Linux host.
