CVE-2019-9349
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 libstagefright, there is a possible resource exhaustion due to improper input validation. This could lead to remote denial of service with no additional execution privileges needed. User interaction is needed for exploitation. Product: AndroidVersions: Android-10Android ID: A-124330204
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 confidenceIn libstagefright (Android's media framework), improper input validation allows a remote attacker to cause resource exhaustion, leading to denial of service. Exploitation requires user interaction, such as processing a specially crafted media file.

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.
-
Confirm Android version is exactly 10.0Check Settings > About Phone > Android version, or run 'adb shell getprop ro.build.version.release'Affected if Version shows anything other than exactly 10.0 (versions before or after 10.0 are not affected)
-
Check security patch levelGo to Settings > About Phone > Security patch level, or run 'adb shell getprop ro.build.version.security_patch'Affected if Patch level is earlier than the date the CVE fix was released (the exact date varies by carrier/device) and version is 10.0
-
Verify libstagefright component is presentRun 'adb shell ls -la /system/lib/libstagefright.so' or check for stagefright processes with 'adb shell ps -A | grep stagefright'Affected if The library file exists (which it does on all Android 10.0 devices by default) - if absent, the vulnerability cannot be triggered
-
Assess media processing exposureReview whether the device processes media files from untrusted sources (e.g., browser downloads, messaging apps, email attachments)Affected if Device regularly processes media files from remote/untrusted sources - exploitation requires a specially crafted media file to be processed
Device is affected only if running Android version 10.0 exactly AND has not received the security update that includes the CVE-2019-9349 fix, AND processes media files from potentially malicious sources.
