Unauthenticated service interruption via unbounded authentication allocations
Published Mar 17, 2026 · Updated Mar 17, 2026
Resource-exhaustion denial of service in IBMi 7.6 allows remote attackers to interrupt service through failed authentication connections. The authentication path allocates resources for failed connections without limits or throttling, allowing repeated failures to exhaust capacity. No credentials or user interaction are required; the reported effect is service interruption, with no data disclosure or modification.
