In process_service_search_attr_rsp of sdp_discovery.cc, there is a possible out of bound read due to a missing bounds check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Security readout for executives and security teams

Plain-English summary

CVE-2018-9449 is an Android information disclosure flaw. A local, low-privileged attacker could trigger an out-of-bounds read in service discovery response handling and potentially read sensitive memory. The sources do not show active exploitation.

Executive priority

Treat this as a moderate legacy Android exposure. It mainly matters where old Android devices remain in use, especially unmanaged or unsupported devices. Prioritize remediation through patch verification and retirement of obsolete endpoints.

Technical view

The issue is a CWE-125 out-of-bounds read in process_service_search_attr_rsp in sdp_discovery.cc, caused by a missing bounds check. CVSS 3.1 is 5.5: local attack vector, low complexity, low privileges, no user interaction, high confidentiality impact only.

Likely exposure

Exposure is limited to Google Android versions 6, 6.0.1, 7, 7.1.1, 7.1.2, 8, and 8.1 that have not received the relevant 2018 Android or Pixel security update.

Exploitation context

The CVSS vector indicates local access and low privileges are required, with no user interaction. The source bundle does not provide exploit code, proof-of-concept status, or evidence of exploitation in the wild. CISA KEV status is false.

Researcher notes

The available evidence identifies the vulnerable function and impact class but not a public exploit path. Validation should focus on version, patch level, and whether vulnerable Android builds remain deployed. Avoid assuming network reachability or remote exploitation from the provided data.

Mitigation direction

  • Inventory Android 6 through 8.1 devices still present in the environment.
  • Apply the relevant Android or Pixel security update from August 2018 or later.
  • Retire or isolate devices that cannot receive security updates.
  • Check vendor guidance for device-specific patch availability and support status.

Validation and detection

  • Confirm Android version and security patch level on managed devices.
  • Verify affected versions are no longer present or are patched.
  • Review mobile device management inventory for unsupported Android builds.
  • Document exceptions for devices that cannot be updated.
