Unauthenticated service interruption via out-of-bounds read

Published Feb 16, 2023 · Updated Jan 27, 2025

Out-of-bounds read in OpenBMC firmware before 0.72 allows remote attackers to interrupt BMC service via network access. Intel identifies the defect only as a firmware out-of-bounds read and does not disclose the affected parser, request field, or failed bounds check. No authentication is required; the published impact is limited to interruption of BMC availability, with no reported data disclosure or modification.
