CVE-2026-29643

The CVE relates to XiangShan’s CSR subsystem (NewCSR) in an open‑source RISC‑V processor. The flaw is an improper exceptional‑condition handling when CSR operations target non‑existent/custom CSR addresses, which may trigger an illegal‑instruction exception but fail to reliably transfer control t...

CVE-2026-29643

XiangShan Open-source high-performance RISC-V processor commit edb1dfaf7d290ae99724594507dc46c2c2125384 2024-11-28 contains an improper exceptional-condition handling flaw in its CSR subsystem NewCSR. On affected versions, certain sequences of CSR operations targeting non-existent/custom CSR...

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...
