CVE-2025-51679 Aug 26, 00:00 CRITICAL Act Now

Information disclosure in the OpenRISC OR1200 processor soft-core (commit 83ac6b) arises from a mismatch between the RTL source and the synthesized netlist, meaning the fabricated/synthesized hardware behaves differently than the verified design and can leak confidential state or misbehave. The flaw was surfaced by the academic SynFuzz RTL-vs-netlist fuzzing research (arXiv:2504.18812) rather than by field exploitation; no public exploit identified at time of analysis and EPSS is low (0.15%, 5th percentile). The NVD CVSS of 9.1 (C:H/A:H) is far more alarming than the vague one-line description supports, so the score should be treated skeptically.
