Name of the Vulnerable Software and Affected Versions Android versions prior to Android-11

Description The issue is related to a missing bounds check in the phNxpNciHal send ext cmd function of phNxpNciHal ext.cc, which could lead to a possible out of bounds write. This might result in local escalation of privilege in the NFC server, requiring System execution privileges for exploitation. No user interaction is needed for exploitation.
