CVE-2025-36744

Physical OS disclosure via bootloader diagnostics

Published Dec 12, 2025 · Updated Dec 12, 2025

Information exposure in SolarEdge SE3680H firmware 4.0 through 4.21 allows physically proximate attackers to read operating system details. During repeated initialization while awaiting boot instructions, the bootloader emits diagnostic output containing unnecessary OS information. Physical access to the device during the bootloader loop is required; the published impact is limited to disclosure, with no integrity or service effect.
