CVE-2026-80358

Unauthorized controller access via SMCU debug interface

Published Sep 28, 2026 · Updated Sep 28, 2026

Debug-interface access flaw in Dell Boot Optimized Server Storage (BOSS) before 2.2.13.2038 allows attackers unauthorized controller access. Dell identifies improper access control on the 17G BOSS-N1 SMCU's on-chip debug and test interface but does not disclose the specific failure or accessible functions. Exploitation requires physical access and user interaction under high-complexity conditions; Dell reports unauthorized access without specifying the accessible resources.
