Summary

Berkeley Out-of-Order Machine (BOOM) commit 5223e44cfeb26f41380057a2eb4d651197475f69 contains a potential incorrect privilege assignment issue in the v3 and v4 NBDTLB implementations. The raw mstatus.SUM value participates in the read and write permission logic without an explicit local satp.MODE validity check at the use site.

Risk Assessment

This could lead to unauthorized memory access, potentially breaking process isolation and system security.

Recommendation

Apply vendor patches and review NBDTLB implementations for correct privilege checking.
