CVE intelligence and bounded remediation

CVE-2018-9428 — In startDevice of AAudioServiceStreamBase.cpp there is a possible out of bounds write due to a use after free

High CVSS 8.4

In startDevice of AAudioServiceStreamBase.cpp there is a possible out of bounds write due to a use after free. This could lead to local arbitrary code execution with no additional execution privileges needed. User interaction is needed for exploitation. https://source.android.com/security/bulletin/2018-07-01

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
