CVE-2025-9709Public exploit

Physical debug access via runtime EM fault injection

Published Sep 5, 2025 · Updated Sep 5, 2025

Improper access control in Nordic Semiconductor nRF52810 version 0 allows physically proximate attackers to bypass APPROTECT via EM fault injection. A single runtime EM pulse causes an approximately 1-microsecond reset that re-enables the SWD debug port while the application continues running. Physical access and fault-injection equipment are required; successful exploitation permits immediate memory dumping or tampering.
