In bnep_data_ind of bnep_main.cc, there is a possible out of bounds read due to a missing bounds check. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, 8.1. Android ID: A-69177251.

Detection & IOCsextracted from sources · hover to see the quote
- →Alert on multiple (e.g. 20+) rapid BNEP control command responses of type BNEP_CONTROL_COMMAND_NOT_UNDERSTOOD (0x00) from the Android Bluetooth process to the same remote peer, which is indicative of the heap-leak enumeration loop. ↗
- →The vulnerability is in bnep_data_ind() in bnep_main.cc; flag any crash or anomalous read in this function on affected AOSP versions 5.1.1 through 8.1 as exploitation evidence. ↗
- ·Exploitation requires no user interaction and no additional execution privileges; the attacker only needs Bluetooth radio proximity to the victim device — no pairing is required. ↗
- ·The exploit PoC must be run as root on the attacker machine due to raw L2CAP socket requirements. ↗
- ·The heap-leak PoC notes that OOB read confirmation may require a debugger attached to the target process; passive network observation alone may not be sufficient to confirm exploitation. ↗
