CVE-2025-30147 is a high-severity consensus bug affecting Hyperledger Besu versions 24.7.1 through 25.2.2, specifically impacting the ALTBN128 precompiles. The vulnerability stems from an insufficient point-on-curve check in the Besu Native gnark-crypto implementation, allowing specially crafted inputs to cause Besu to produce incorrect results and fall out of consensus. This could lead to homogeneous Besu-only networks enshrining invalid state. The CVSS score of 8.7 (HIGH) indicates a critical risk, with a network attack vector and low attack complexity, potentially leading to high integrity impact. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
