Answer in brief
CVE-2026-18509 records a Unknown severity vulnerability in IBM i is Affected By A Prvilege Escalation Vulnerability []. The current sources do not mark it as known exploited. The current feed maps IBM/i (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
