NEMU 安全漏洞

NEMU is an open-source teaching system simulator developed by XiangShan. Previous versions of NEMU 55295c4 contained security vulnerabilities. These vulnerabilities stemmed from improper handling of writes to sie CSR when the RVH extension was enabled. This improper handling could affect the...

CVE-2026-29649

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...

PT-2026-33839

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-2026-29646

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...

SP1 安全漏洞

SP1 is an open-source zero-knowledge virtual machine developed by Succinct. Versions 6.0.0 to 6.0.2 of SP1 contain security vulnerabilities. These vulnerabilities stem from defects in the recursive sharding verifier, which could allow malicious provers to construct invalid proofs...

CVE-2026-40323 SP1 V6 Recursion Circuit Row-Count Binding Gap

SP1 is a zero‑knowledge virtual machine that proves the correct execution of programs compiled for the RISC-V architecture. In versions 6.0.0 through 6.0.2, a soundness vulnerability in the SP1 V6 recursive shard verifier allows a malicious prover to construct a recursive proof from a shard proof...

CVE-2026-40323

SP1 (zero‑knowledge VM) has a soundness vulnerability in the V6 recursive shard verifier affecting versions 6.0.0–6.0.2, allowing a malicious prover to construct a recursive proof from a shard proof that the native verifier would reject. The issue is fixed in version 6.1.0. Impact is described as...
