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 · unedited
In Content, there is a possible way to determinate the user's account due to side channel information disclosure. This could lead to local information disclosure with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-199751919

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 confidence

Side-channel vulnerability in Android's Content component allows local attackers to determine user accounts through timing or other side-channel information leakage. Exploitation requires local device access with user-level execution privileges but needs no user interaction.

MitigationApply Android security updates (patch level after August 2022); this OS-level vulnerability requires system-level patching rather than configuration changes.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Android version number
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Version is exactly 13.0 (Android 13)
  2. Verify security patch level
    Go to Settings > About Phone > Security Patch Level, or run 'getprop ro.build.version.security_patch' via ADB shell
    Affected if Patch level is August 2022 or earlier (format: YYYY-MM-DD)
  3. Confirm Content component exposure
    Verify the device has Content component accessible to local apps: check if apps can access content providers without restrictions via 'pm list packages -3' to see installed third-party apps with potential content access
    Affected if Device runs Android 13.0 with security patch level on or before August 2022 and has third-party apps installed that could access content providers

A user is affected if their Android device runs version 13.0 with a security patch level dated August 2022 or earlier, as the side-channel in the Content component can be exploited by any local app with standard user privileges.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Android security updates (patch level after August 2022); this OS-level vulnerability requires system-level patching rather than configuration changes.

Recommended fix Moderate confidence

Android 14 or later (or latest Android 13 security patch level)

  1. 1. Check the current Android version on the affected device by going to Settings > About Phone > Android version
  2. 2. If the device supports Android 14, perform a system update to Android 14 or later by going to Settings > System > Software Update
  3. 3. If Android 14 is not available for the device, apply the latest monthly security patch available for Android 13 through Settings > System > Software Update > Check for updates
  4. 4. Verify the update was applied successfully by checking Settings > About Phone > Android version shows the patched level
Caveat Upgrading to a new Android major version may cause incompatibility with some apps or settings; ensure backup before updating
