Physical unauthorized access via SMCU debug interface
Published Sep 28, 2026 · Updated Sep 28, 2026
Debug access-control failure in Dell Boot Optimized Storage Solution (BOSS) before 2.2.13.2038 grants physically proximate attackers SMCU access. The SMCU on 17G BOSS-N1 controllers does not properly control its on-chip debug and test interface; Dell has not disclosed the exact bypass operation. Exploitation requires physical access and user interaction, and Dell does not identify which controller resources become reachable.
