Insufficient API bounds checking in phalFelica in NXP NXPNfcRdLib RC663 through 07.14.00_Pub may allow an attacker with privileges or an untrusted third party to access unintended memory regions, potentially leading to limited loss of confidentiality, integrity, and availability. All software versions from 07.18.00 onwards have fixed this problem.
