XiangShan 安全漏洞

XiangShan is an open-source high-performance RISC-V processor project developed by XiangShan in China. There is a security vulnerability in XiangShan, which stems from specially crafted read and write operations on the menvcfg structure, potentially causing the WPRI bit to be set unexpectedly,...

CVE-2026-29645

NEMU OpenXiangShan/NEMU before v2025.12.r2 contains an improper instruction-validation flaw in its RISC-V Vector RVV decoder. The decoder does not correctly validate the funct3 field when decoding vsetvli/vsetivli/vsetvl, allowing certain invalid OP-V instruction encodings to be misinterpreted an...

PT-2026-33830

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...
