In OpenXiangShan NEMU, insufficient Smstateen permission enforcement allows lower-privileged code to access IMSIC state via stopei/vstopei CSRs even when mstateen0.IMSIC is cleared, potentially enabling cross-context information leakage or disruption of interrupt handling.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
