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 use after free due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07202891; Issue ID: ALPS07202891.

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

A use-after-free vulnerability exists in the aee (Android Error Analyzer) component on MediaTek devices due to a missing bounds check. The flaw allows a local attacker with System execution privileges to escalate privileges further. No user interaction is required for exploitation.

MitigationApply the vendor patch ALPS07202891 through a system/firmware update. Since this is a system-level component vulnerability affecting MediaTek ALPS implementations, contact the device manufacturer for the appropriate firmware update.

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 the chipset vendor
    Check the device specifications or use a system info app to confirm the SoC manufacturer. Look for 'MediaTek' or 'MTK' in the processor/hardware details.
    Affected if The device does NOT use a MediaTek chipset - this vulnerability is specific to MediaTek implementations.
  2. Verify the Android version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell.
    Affected if The installed Android version is exactly 11.0 or 12.0 - only these specific versions are affected.
  3. Confirm the aee component is present
    Check for the aee daemon or service. Run 'ls -la /system/bin/aee' or 'ls -la /vendor/bin/aee' via ADB shell, or check for the 'aee' process running with 'ps -A | grep aee'.
    Affected if The aee (Android Error Analyzer) binary or service exists on the device - this is the vulnerable component.
  4. Check current execution context
    Determine the privilege level of the process attempting to exploit this. This requires system-level access. Use 'id' command or check process privileges via ADB.
    Affected if The attacker has System-level execution privileges (not root, but system_server level or above) - this is required for exploitation.

A user is affected if their MediaTek device runs Android 11.0 or 12.0, has the aee component present, and the potential attacker already has System-level execution privileges on that device.

Mitigation

Apply the vendor patch ALPS07202891 through a system/firmware update. Since this is a system-level component vulnerability affecting MediaTek ALPS implementations, contact the device manufacturer for the appropriate firmware update.

Recommended fix High confidence

Android 11.0/12.0 with July 2022 Android Security Bulletin patch (or subsequent patch containing ALPS07202891)

  1. 1. Check the current Android security patch level on affected devices (Settings > About Phone > Security Patch Level)
  2. 2. Apply the July 2022 Android Security Update or later, which contains the MediaTek patch for CVE-2022-32607 (Patch ID: ALPS07202891)
  3. 3. Verify the security patch level has been updated to July 2022 or later
  4. 4. Confirm the aee component has been updated as part of the system update
Caveat Standard Android security update; no expected breaking changes for this patch
