CVE-2026-29642

A local attacker who can execute privileged CSR operations or can induce firmware to do so performs carefully crafted reads/writes to menvcfg e.g., csrrs in M-mode. On affected XiangShan versions commit aecf601e803bfd2371667a3fb60bfcd83c333027, 2024-11-19, these menvcfg accesses can unexpectedly...

CVE-2026-29648

In OpenXiangShan NEMU, when Smstateen is enabled, clearing mstateen0.ENVCFG does not correctly restrict access to henvcfg and senvcfg. As a result, less-privileged code may read or write these CSRs without the required exception, potentially bypassing intended state-enable based isolation control...
