In handle_app_cur_val_response of dtif_rc.cc, there is a possible stack buffer overflow due to a missing bounds check. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.

Security readout for executives and security teams

Plain-English summary

CVE-2018-9418 is a high-severity Android flaw in older Android releases. A missing bounds check can cause a stack buffer overflow and potentially allow remote code execution. The source states no user interaction and no extra privileges are needed, but the CVSS vector indicates adjacent-network reachability rather than internet-wide exposure.

Executive priority

Treat this as a high-priority legacy Android remediation item. The likely business risk is concentrated in older mobile fleets, kiosks, embedded Android systems, or unmanaged devices that missed OEM security updates.

Technical view

The issue is in handle_app_cur_val_response in dtif_rc.cc and is classified as CWE-120. A missing bounds check may permit stack buffer overflow leading to code execution. CVSS 3.1 is 8.8, with adjacent attack vector, low complexity, no privileges, no user interaction, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is most relevant to devices running Android 7, 7.1.1, 7.1.2, 8, or 8.1 that lack the relevant Android or OEM security update. Newer Android versions are not listed as affected in the supplied record.

Exploitation context

The supplied sources do not show CISA KEV listing or active exploitation. The vulnerability is still serious because the record describes unauthenticated, no-click remote code execution potential within adjacent-network reach.

Researcher notes

The evidence identifies the vulnerable function, weakness class, affected Android versions, and CVSS vector. The public bundle does not provide exploit details, proof of active exploitation, or detailed patch mechanics beyond the Android security bulletin reference.

Mitigation direction

  • Check Android and OEM advisories for CVE-2018-9418 coverage.
  • Apply the applicable July 2018 or later Android security update.
  • Retire or isolate Android 7.x and 8.x devices that cannot be updated.
  • Prioritize managed, exposed, or high-value devices on legacy Android versions.

Validation and detection

  • Inventory Android devices and record OS versions and patch levels.
  • Confirm whether any devices run Android 7, 7.1.1, 7.1.2, 8, or 8.1.
  • Verify vendor security bulletin coverage for each device model.
  • Flag devices without a relevant Android or OEM security patch.
  • Document compensating controls for devices that cannot be updated.
