Partial service interruption via unthrottled handle allocation
Published Aug 28, 2026 · Updated Aug 28, 2026
Denial of service in NetApp StorageGRID 11.5 and higher allows remote authenticated users to partially interrupt storage service. The affected code allocates file descriptors or handles without limits or throttling, although NetApp has not disclosed the component or triggering input. Exploitation requires a non-standard configuration, high-complexity conditions, and some attacker control over the environment; no data disclosure or modification is reported.
