CVE-2026-107674
MediumCVSS 5.1Summary
IBM i versions 7.3, 7.4, 7.5, and 7.6 is vulnerable to a denial of service to Digital Certificate Manager (DCM) for System TLS using applications attempting to create secure network connections. A bad actor could use this to prevent a service from starting or cause it to fall back to non-secure connections.
Risk Assessment
An attacker may prevent a service from starting or force a fallback to non-secure connections, potentially causing service disruption and weakening communication security.
Recommendation
Apply available IBM fixes for IBM i 7.3, 7.4, 7.5, and 7.6 addressing DCM for System TLS.
