A security vulnerability has been identified in the pkcs11-provider, which is associated with Public-Key Cryptography Standards (PKCS#11). If exploited successfully, this vulnerability could result in a Bleichenbacher-like security flaw, potentially enabling a side-channel attack on PKCS#1 1.5 decryption.
The device does not contain sufficient protection mechanisms to prevent physical side channels from exposing sensitive information due to patterns in physically observable phenomena such as variations in power consumption, electromagnetic emissions (EME), or acoustic emissions.
The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor, which exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not.
