FreeRDP 3.0.0 before 3.32.0 contains a heap buffer overflow vulnerability in collect_keys() that allows local attackers to write past the fixed 64-entry keys array during PKCS#11 key enumeration. Attackers controlling smartcard tokens can present more than 64 public key objects across multiple slots to corrupt heap memory with attacker-chosen CKA_ID and CKA_LABEL data during smartcard logon.
