CNA source text (English)
QSPI flash encryption side-channel leakage
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.
