Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

btif/src/btif_dm.c in Android before 5.1 does not properly enforce the temporary nature of a Bluetooth pairing, which allows user-assisted remote attackers to bypass intended access restrictions via crafted Bluetooth packets after the tapping of a crafted NFC tag.
