    The use-after-free vulnerability was found in the AuthentIC driver in OpenSC packages, occuring in the     card enrolment process using pkcs15-init when a user or administrator enrols or modifies cards. An     attacker must have physical access to the computer system and requires a crafted USB device or smart card     to present the system with specially crafted responses to the APDUs, which are considered high complexity     and low severity. This manipulation can allow for compromised card management operations during enrolment.
