EUVD-2026-23958

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...

EUVD-2026-23944

NEMU contains an implementation flaw in its RISC-V Hypervisor CSR handling where henvcfg7:4 CBIE/CBCFE/CBZE-related fields is incorrectly masked/updated based on menvcfg7:4, so a machine-mode write to menvcfg can implicitly modify the hypervisor's environment configuration. This can lead to...

NEMU 安全漏洞

NEMU is an open-source teaching system simulator developed by XiangShan. NEMU has a security vulnerability, which stems from implementation defects in the RISC-V Hypervisor CSR. This defect may lead to incorrect virtualization configuration execution, causing unexpected traps or denial-of-service...

CVE-2026-29649

The CVE concerns NEMU’s RISC-V Hypervisor CSR handling. Specifically, henvcfg[7:4] (CBIE/CBCFE/CBZE fields) is incorrectly masked/updated by menvcfg[7:4], so a machine-mode write to menvcfg can implicitly modify the hypervisor environment configuration. This can cause incorrect enforcement of vir...

CVE-2026-29646

OpenXiangShan NEMU is affected by CVE-2026-29646 prior to the 55295c4 commit. With RVH (Hypervisor extension) enabled, a VS-mode guest write to the supervisor interrupt-enable CSR (sie) may be handled incorrectly, potentially influencing the machine-level interrupt enable (mie) state. This underm...

SUSE CVE-2023-20585

Insufficient checks of the RMP on host buffer access in IOMMU may allow an attacker with privileges and a compromised hypervisor to trigger an out of bounds condition without RMP checks, resulting in a potential loss of confidential guest integrity...
