Security readout for executives and security teams
Plain-English summary
A malformed media file with ID3 metadata could make affected Android versions consume resources and crash or hang media parsing. The user must open or process the file, and sources describe denial of service only, not data theft or code execution.
Executive priority
Treat as a moderate availability risk for legacy Android assets. It is not presented as remote code execution or data compromise, but unsupported devices should be remediated or retired through normal vulnerability management.
Technical view
In Android ID3.cpp, removeUnsynchronization improperly validates input, allowing resource exhaustion. CVSS 3.1 is 5.5: local attack vector, low complexity, no privileges, user interaction required, and high availability impact only.
Likely exposure
Exposure is mainly legacy Android 6, 6.0.1, 7, 8, 8.1, and listed development branches. Modern, fully patched Android estates are less likely exposed, but unmanaged or embedded Android devices may remain at risk.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not marked KEV. Exploitation requires user interaction and would affect availability, such as causing a crash or hang during media metadata handling.
Researcher notes
Key constraints are local attack vector and required user interaction. The public bundle identifies CWE-400 and the vulnerable Android ID3.cpp function but does not provide detailed patch diffs, exploit evidence, or product-specific OEM status.
Mitigation direction
- Apply Android vendor security updates covering the July 2018 bulletin or later.
- Inventory Android 6 through 8.1 devices and embedded Android builds.
- Prioritize unmanaged, kiosk, media-handling, and long-lived Android devices.
- Check OEM guidance where Android patch availability differs by device.
Validation and detection
- Confirm Android security patch level against the July 2018 bulletin.
- Identify devices running affected Android versions listed in the CVE.
- Review crash telemetry for media metadata parsing failures.
- Verify mobile device management reports include legacy and embedded devices.

Uncontrolled Resource Consumption
Uncontrolled Resource Consumption represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
