CVE-2019-2097
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn HAliasAnalyzer.Query of hydrogen-alias-analysis.h, there is possible memory corruption due to type confusion. This could lead to remote code execution from a malicious proxy configuration, with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android-7.0 Android-7.1.1 Android-7.1.2 Android-8.0 Android-8.1 Android-9. Android ID: A-117606285.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceType confusion in HAliasAnalyzer.Query within Android's hydrogen (Bluetooth) stack leads to memory corruption. A malicious proxy configuration can trigger this to achieve remote code execution without user interaction or elevated privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Android version is in affected rangeGo to Settings > About Phone > Android version. Confirm the version is 7.0, 7.1.1, 7.1.2, 8.0, 8.1, or 9.0.Affected if The installed Android version matches one of these exact versions: 7.0, 7.1.1, 7.1.2, 8.0, 8.1, or 9.0
-
Confirm Bluetooth is enabledCheck if Bluetooth is turned on in Settings > Bluetooth, or run 'settings get global bluetooth_on' via ADB shell.Affected if Bluetooth is enabled or was recently enabled on the device
-
Check Android security patch levelGo to Settings > About Phone > Security patch level. Compare the date to the fix release for CVE-2019-2097.Affected if The security patch level predates the fix for CVE-2019-2097, or the patch level is unknown/unset
The device is likely affected if it runs Android 7.0-9.0, has Bluetooth enabled, and lacks the security update addressing this Bluetooth stack vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the Android security patch level for the affected versions (Android 7.0-9) that addresses CVE-2019-2097. Prioritize patching given the critical CVSS score and low attack complexity.
Android 10 (API level 29) or later
- Identify the current Android version running on the affected device
- Back up all important data and settings
- Ensure the device is connected to a stable power source
- Check for system updates: Go to Settings > System > Software Update (or Settings > About Phone > System Updates)
- Download and install the available Android update
- After update completes, verify the device is running Android 10 or later
