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 aee daemon, there is a possible information disclosure due to a path traversal. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06419017; Issue ID: ALPS06270870.

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 · high confidence

A path traversal vulnerability in the aee daemon allows local attackers to read arbitrary files on the system by manipulating file paths to escape the intended directory boundaries, leading to local information disclosure without requiring elevated privileges or user interaction.

MitigationApply vendor patch ALPS06419017 to address the path traversal vulnerability in the aee daemon; if immediate patching is not feasible, restrict physical and local access to affected devices and monitor for suspicious file access patterns.

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. Identify Android version
    Navigate to Settings > About Phone > Android version (or use 'getprop ro.build.version.release' via ADB shell)
    Affected if The reported version is 11.0 or 12.0 exactly
  2. Locate aee daemon
    Check if the aee daemon exists on the device by searching for 'aee' in /system/bin or /vendor/bin (or use 'find / -name '*aee*' 2>/dev/null' via ADB shell with root)
    Affected if The aee daemon binary is present on the device
  3. Verify daemon is running
    Run 'ps -A | grep aee' or 'ps -ef | grep aee' via ADB shell to check if the aee daemon process is actively running
    Affected if The aee daemon process is currently executing
  4. Check for unauthorized file access logs
    Review logcat output or system logs (particularly /data/log/ or /data/dumpstate/) for unusual file read operations referencing the aee daemon (look for 'open' or 'read' syscalls with suspicious paths like ../../)
    Affected if Logs show the aee daemon accessing files outside its intended directory (path traversal patterns)

The device is affected if it runs Android version 11.0 or 12.0 and contains the aee daemon, which could allow a local attacker to read arbitrary files via path traversal.

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

Apply vendor patch ALPS06419017 to address the path traversal vulnerability in the aee daemon; if immediate patching is not feasible, restrict physical and local access to affected devices and monitor for suspicious file access patterns.

Recommended fix Moderate confidence
  1. Check the Android Security Patch Level on the device to confirm if the May 2022 or later security patch is installed
  2. If the device is on Android 11.0 or 12.0 with MediaTek chipset, contact the device manufacturer or MediaTek for the specific patch (ALPS06419017)
  3. Apply the vendor-supplied security update that includes the fix for ALPS06419017
  4. Verify the patch has been applied by checking the Android Security Patch Level in Settings > About Phone > Android version
