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, there is a possible permission bypass due to a missing permission check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08487630; Issue ID: MSV-1020.

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

This is a permission bypass vulnerability in aee (Android Exception Engine), where a missing permission check allows a local attacker with System execution privileges to escalate privileges to a higher level. The vulnerability does not require user interaction and enables local privilege escalation.

MitigationApply patch ALPS08487630 which adds the missing permission check in the aee component. This is a vendor-specific fix for MediaTek/ALPS platforms.

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
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version
    Affected if Version equals 12.0, 13.0, or 14.0
  2. Verify device uses MediaTek chipset
    Run 'getprop ro.hardware' or check /proc/cpuinfo for MediaTek platform identifier
    Affected if Device is MediaTek/ALPS based (this vulnerability is platform-specific)
  3. Confirm aee component is present
    Check for /system/bin/aee or /vendor/bin/aee binary, or run 'ls -la /system/bin/aee 2>/dev/null'
    Affected if aee binary exists and is executable on the device
  4. Check aee module version
    Run 'aee -v' or check /system/lib/libaee.so version info if available
    Affected if Unable to determine version or version predates patch ALPS08487630

Device is affected if running Android 12.0/13.0/14.0 on a MediaTek/ALPS platform with the aee component present and missing the ALPS08487630 patch.
