Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Smart card APDU transport or protocol errors passed to validation functions were ignored. This allowed failed card transactions or disconnected states to be interpreted as successful authentication or execution.
Auth Bypass: Privileged applet lifecycle operations (such as loading and deleting card applications) could be executed without asserting that a secure, authenticated channel had actually been established.
Cryptographic Issues: Off-by-one errors in coordinate indexing (e.g., retrieving parity from byte 63 instead of 64) during public key compression and lack of truncation for signature components can cause verification panics or standard-compliance failures.
