CVE-2018-9485: In l2cble_process_sig_cmd of l2c_ble.cc, there is a possible out of bounds read due to a missing bounds check.

In l2cble_process_sig_cmd of l2c_ble.cc, there is a possible out of bounds read due to a missing bounds check. This could lead to remote information disclosure over bluetooth with no additional execution privileges needed. User interaction is not needed for exploitation.

Security readout for executives and security teams

Plain-English summary

This Android Bluetooth flaw could let a nearby attacker read sensitive memory from affected devices without user interaction. It is not internet-routable, but it matters for fleets with older Android devices or unmanaged Bluetooth exposure.

Executive priority

Treat as a moderate fleet hygiene issue. Prioritize legacy Android devices used near sensitive people, facilities, or data, but do not treat it as proven widespread exploitation from these sources.

Technical view

CVE-2018-9485 is a CWE-125 out-of-bounds read in Android's l2cble_process_sig_cmd in l2c_ble.cc. The CVSS vector is AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, reflecting adjacent Bluetooth access and high confidentiality impact only.

Likely exposure

Exposure is most likely on Android 7, 8, 8.1, and 9 devices, including listed development branches, that have not received the relevant Android security update.

Exploitation context

The source states remote information disclosure over Bluetooth with no privileges or user interaction. KEV is false, and the provided sources do not establish active exploitation.

Researcher notes

The available evidence identifies the vulnerable function and impact class, but does not provide exploit details or device-specific patch matrices. Validation should focus on patch level, Android version, and vendor support status.

Mitigation direction

  • Apply Android security updates from the September 2018 bulletin or later vendor-supported builds.
  • Retire or isolate affected Android versions where patch status cannot be verified.
  • Restrict Bluetooth use on unsupported devices that must remain in service.
  • Check device vendor guidance for model-specific patch availability and backports.

Validation and detection

  • Inventory Android version, build, and security patch level across managed devices.
  • Compare devices against Google's September 2018 Android Security Bulletin guidance.
  • Prioritize validation for devices with Bluetooth enabled in sensitive environments.
  • Confirm compensating controls for devices that cannot be patched or retired.
