Who should care

Android device owners, mobile fleet administrators, OEM/ROM maintainers, and security teams responsible for patching supported Android builds should prioritize this issue on affected versions.

Technical summary

NVD maps CVE-2017-0418 to CWE-787 and assigns CVSS 3.0 vector CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The vulnerability is described as an elevation of privilege flaw in Audioserver that could allow a local malicious app to execute arbitrary code within a privileged process. NVD lists affected Android CPEs from 4.4.4 through 7.1.1, indicating broad exposure across multiple Android release lines.

Defensive priority

High. This is a local privilege-escalation issue in a privileged Android component with high impact on confidentiality, integrity, and availability, so patching should be prioritized on any still-supported affected device.

Recommended defensive actions

  • Apply the Android security update associated with the 2017-02-01 Android security bulletin or a later patched build.
  • Confirm affected devices are running a vendor build that includes the fix for CVE-2017-0418.
  • Prioritize remediation on devices that allow third-party app installation or have broader exposure to untrusted apps.
  • Track fleet compliance for Android versions listed as affected by NVD: 4.4.4 through 7.1.1.
  • Use standard mobile app governance controls to reduce exposure to untrusted applications until patching is complete.
