Summary

IBM i versions 7.3, 7.4, 7.5, and 7.6 are affected. Improper locking (CWE-667) in Digital Certificate Manager (DCM) for System TLS lets a local user with high privileges cause a denial of service when applications try to create secure network connections. A bad actor could use this to prevent a service from starting or to force it to fall back to non-secure connections.
