Security is not absolute. Even cryptographic hardware can be vulnerable.

Yubico for example had to replace many of their YubiKeys after a vulnerability was detected in its secure element firmware which affected the strength of keys generated on the device. They sent me a replacement YubiKey after I contacted them.
