CVE-2022-34430

System interruption via unrestricted UI archive expansion

Published Oct 11, 2022 · Updated May 19, 2025

Zip bomb processing in the Dell Hybrid Client UI before 1.8 allows local users with guest access to interrupt the system. Dell identifies the UI as the affected component but does not disclose the archive-processing code path or its missing expansion limit. A local guest session is sufficient to trigger the availability impact; the published assessment reports no confidentiality or integrity impact.
