Summary

Any application that uses external QSPI flash for encrypted XIP on nRF5340 and relies on that encryption for confidentiality and/or integrity of the externally stored code. No specific nRF Connect SDK version is the root cause; the weakness is in the on-the-fly decryption scheme.

Risk Assessment

An attacker with physical access to the device may read or modify code stored in external flash, potentially compromising software confidentiality and integrity.

Recommendation

It is recommended to implement additional protections such as secure boot and integrity checks, and consider using internal flash or other protection mechanisms.
