An out-of-bounds read vulnerability was found in OpenSC packages within the
MyEID driver when handling symmetric key encryption. Exploiting this flaw
requires an attacker to have physical access to the computer and a
specially crafted USB device or smart card. This flaw allows the attacker
to manipulate APDU responses and potentially gain unauthorized access to
sensitive data, compromising the system’s security.
