CVE-2025-46638Network attack vector

Service interruption via unbounded TLS session cache

Published Jun 4, 2026 · Updated Jun 4, 2026

Resource exhaustion in Dell BSAFE SSL-J before 7.4 allows remote attackers to interrupt TLS-enabled Java services. The TLS session cache accepts new sessions while allocating resources without an enforced size limit, allowing attacker-driven cache growth to exhaust the hosting process. No authentication or user interaction is required; the published impact is availability loss, with no reported data disclosure or modification.
