CVE-2026-94582

Routing daemon crash via FSPF diagnostic overflow

Published Oct 8, 2026 · Updated Oct 8, 2026

Buffer overflow in Brocade Fabric OS FSPF diagnostics before 10.0.1 allows local users to crash the routing daemon. Internal diagnostic and route-validation routines process diagnostic state payloads beyond allocated memory boundaries. The path is unavailable through standard interfaces or CLI commands and requires another vulnerability to reach; Broadcom also identifies code execution in the daemon as a possible consequence.
