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...

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

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...

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...

CVE-2026-23425

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix ID register initialization for non-protected pKVM guests In protected mode, the hypervisor maintains a separate instance of the kvm structure for each VM. For non-protected VMs, this structure is initialized from...

CVE-2026-23425

CVE-2026-23425 (Linux kernel KVM arm64) — The issue stems from non-protected pKVM guests where the hypervisor copies only the KVM_ARCH_FLAG_ID_REGS_INITIALIZED flag from the host to the hypervisor during pkvm_init_features_from_host, while the actual id_regs data are not initialized. This can cau...
