CVE-2026-29646

OpenXiangShan NEMU (prior to version 55295c4 ) contains a security vulnerability when running with the RVH (Hypervisor extension) enabled. An incorrectly handled write by a VS-mode guest to the supervisor interrupt-enable CSR (sie) can improperly influence the machine-level interrupt enable state...

CVE-2026-29646

In OpenXiangShan NEMU prior to 55295c4, when running with RVH Hypervisor extension enabled, a VS-mode guest write to the supervisor interrupt-enable CSR sie may be handled incorrectly and can influence machine-level interrupt enable state mie. This breaks privilege/virtualization isolation and ca...

CVE-2026-29647

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...
